+# Contributing to LAMMPS via GitHub
+
+Thank your for considering to contribute to the LAMMPS software project.
+
+The following is a set of guidelines as well as explanations of policies and workflows for contributing to the LAMMPS molecular dynamics software project. These guidelines focus on submitting issues or pull requests on the LAMMPS GitHub project.
+
+Thus please also have a look at:
+* [The Section on submitting new features for inclusion in LAMMPS of the Manual](http://lammps.sandia.gov/doc/Section_modify.html#mod-15)
+* [The LAMMPS GitHub Tutorial in the Manual](http://lammps.sandia.gov/doc/tutorial_github.html)

+## I don't want to read this whole thing I just have a question!
+
+> **Note:** Please do not file an issue to ask a general question about LAMMPS, its features, how to use specific commands, or how perform simulations or analysis in LAMMPS. Instead post your question to the ['lammps-users' mailing list](http://lammps.sandia.gov/mail.html). You do not need to be subscribed to post to the list (but a mailing list subscription avoids having your post delayed until it is approved by a mailing list moderator). Most posts to the mailing list receive a response within less than 24 hours. Before posting to the mailing list, please read the [mailing list guidelines](http://lammps.sandia.gov/guidelines.html). Following those guidelines will help greatly to get a helpful response. Always mention which LAMMPS version you are using.
+
+## How Can I Contribute?
+
+There are several ways how you can actively contribute to the LAMMPS project: you can discuss compiling and using LAMMPS, and solving LAMMPS related problems with other LAMMPS users on the lammps-users mailing list, you can report bugs or suggest enhancements by creating issues on GitHub (or posting them to the lammps-users mailing list), and you can contribute by submitting pull requests on GitHub or e-mail your code
+to one of the [LAMMPS core developers](http://lammps.sandia.gov/authors.html). As you may see from the aforementioned developer page, the LAMMPS software package includes the efforts of a very large number of contributors beyond the principal authors and maintainers.
+
+### Discussing How To Use LAMMPS
+
+The LAMMPS mailing list is hosted at SourceForge. The mailing list began in 2005, and now includes tens of thousands of messages in thousands of threads. LAMMPS developers try to respond to posted questions in a timely manner, but there are no guarantees. Please consider that people live in different timezone and may not have time to answer e-mails outside of their work hours.
+You can post to list by sending your email to lammps-users at lists.sourceforge.net (no subscription required), but before posting, please read the [mailing list guidelines](http://lammps.sandia.gov/guidelines.html) to maximize your chances to receive a helpful response.
+
+Anyone can browse/search previous questions/answers in the archives. You do not have to subscribe to the list to post questions, receive answers (to your questions), or browse/search the archives. You **do** need to subscribe to the list if you want emails for **all** the posts (as individual messages or in digest form), or to answer questions yourself. Feel free to sign up and help us out! Answering questions from fellow LAMMPS users is a great way to pay back the community for providing you a useful tool for free, and to pass on the advice you have received yourself to others. It improves your karma and helps you understand your own research better.
+
+If you post a message and you are a subscriber, your message will appear immediately. If you are not a subscriber, your message will be moderated, which typically takes one business day. Either way, when someone replies the reply will usually be sent to both, your personal email address and the mailing list. When replying to people, that responded to your post to the list, please always included the mailing list in your replies (i.e. use "Reply All" and **not** "Reply"). Responses will appear on the list in a few minutes, but it can take a few hours for postings and replies to show up in the SourceForge archive. Sending replies also to the mailing list is important, so that responses are archived and people with a similar issue can search for possible solutions in the mailing list archive.
+
+### Reporting Bugs
+
+While developers writing code for LAMMPS are careful to test their code, LAMMPS is such a large and complex software, that it is impossible to test for all combinations of features under all normal and not so normal circumstances. Thus bugs do happen, and if you suspect, that you have encountered one, please try to document it and report it as an [Issue](https://github.com/lammps/lammps/issues) on the LAMMPS GitHub project web page. However, before reporting a bug, you need to check whether this is something that may have already been corrected. The [Latest Features and Bug Fixes in LAMMPS](http://lammps.sandia.gov/bug.html) web page lists all significant changes to LAMMPS over the years. It also tells you what the current latest development version of LAMMPS is, and you should test whether your issue still applies to that version.
+
+When you click on the green "New Issue" button, you will be provided with a text field, where you can enter your message. That text field with contain a template with several headlines and some descriptions. Keep the headlines that are relevant to your reported potential bug and replace the descriptions with the information as suggested by the descriptions.
+You can also attach small text files (please add the file name extension `.txt` or it will be rejected), images, or small compressed text files (using gzip, do not use RAR or 7-ZIP or similar tools that are uncommon outside of Windows machines). In many cases, bugs are best illustrated by providing a small input deck (do **not** attach your entire production input, but remove everything that is not required to reproduce the issue, and scale down your system size, that the resulting calculation runs fast and can be run on small desktop quickly).
+
+To be able to submit an issue on GitHub, you have to register for an account (for GitHub in general). If you do not want to do that, or have other reservations against submitting an issue there, you can - as an alternative and in decreasing preference - either send an e-mail to the lammps-users mailing list, the original authors of the feature that you suspect to be affected, or one or more of the core LAMMPS developers.
+
+### Suggesting Enhancements
+
+The LAMMPS developers welcome suggestions for enhancements or new features. These should be submitted using the [GitHub Issue Tracker](https://github.com/lammps/lammps/issues) of the LAMMPS project. This is particularly recommended, when you plan to implement the feature or enhancement yourself, as this allows to coordinate in case there are other similar or conflicting ongoing developments.
+The LAMMPS developers will review your submission and consider implementing it. Whether this will actually happen depends on many factors: how difficult it would be, how much effort it would take, how many users would benefit from it, how well the individual developer would understand the underlying physics of the feature, and whether this is a feature that would fit into a software like LAMMPS, or would be better implemented as a separate tool. Because of these factors, it matters how well the suggested enhancement is formulated and the overall benefit is argued convincingly.

+To be able to submit an issue on GitHub, you have to register for an account (for GitHub in general). If you do not want to do that, or have other reservations against submitting an issue there, you can - as an alternative - send an e-mail to the lammps-users mailing list.
+
+### Contributing Code
+
+We encourage users to submit new features or modifications for LAMMPS to the core developers so they can be added to the LAMMPS distribution. The preferred way to manage and coordinate this is by submitting a pull request at the LAMMPS project on GitHub. For any larger modifications or programming project, you are encouraged to contact the LAMMPS developers ahead of time, in order to discuss implementation strategies and coding guidelines, that will make it easier to integrate your contribution and result in less work for everybody involved. You are also encouraged to search through the list of open issues on GitHub and submit a new issue for a planned feature, so you would not duplicate the work of others (and possibly get scooped by them) or have your work duplicated by others.
+
+How quickly your contribution will be integrated depends largely on how much effort it will cause to integrate and test it, how much it requires changes to the core code base, and of how much interest it is to the larger LAMMPS community. Please see below for a checklist of typical requirements. Once you have prepared everything, see [this tutorial](http://lammps.sandia.gov/doc/tutorial_github.html)
+ for instructions on how to submit your changes or new files through a GitHub pull request
+
+Here is a checklist of steps you need to follow to submit a single file or user package for our consideration. Following these steps will save both you and us time. See existing files in packages in the source directory for examples. If you are uncertain, please ask on the lammps-users mailing list.
+
+* All source files you provide must compile with the most current version of LAMMPS with multiple configurations. In particular you need to test compiling LAMMPS from scratch with `-DLAMMPS_BIGBIG` set in addition to the default `-DLAMMPS_SMALLBIG` setting. Your code will need to work correctly in serial and in parallel using MPI.
+* For consistency with the rest of LAMMPS and especially, if you want your contribution(s) to be added to main LAMMPS code or one of its standard packages, it needs to be written in a style compatible with other LAMMPS source files. This means: 2-character indentation per level, no tabs, no lines over 80 characters. I/O is done via the C-style stdio library, class header files should not import any system headers outside <stdio.h>, STL containers should be avoided in headers, and forward declarations used where possible or needed. All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. Header files must not import namespaces with using. This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.
+* If you want your contribution to be added as a user-contributed feature, and it is a single file (actually a `<name>.cpp` and `<name>.h` file) it can be rapidly added to the USER-MISC directory. Include the one-line entry to add to the USER-MISC/README file in that directory, along with the 2 source files. You can do this multiple times if you wish to contribute several individual features.
+* If you want your contribution to be added as a user-contribution and it is several related features, it is probably best to make it a user package directory with a name like USER-FOO. In addition to your new files, the directory should contain a README text file. The README should contain your name and contact information and a brief description of what your new package does. If your files depend on other LAMMPS style files also being installed (e.g. because your file is a derived class from the other LAMMPS class), then an Install.sh file is also needed to check for those dependencies. See other README and Install.sh files in other USER directories as examples. Send us a tarball of this USER-FOO directory.
+* Your new source files need to have the LAMMPS copyright, GPL notice, and your name and email address at the top, like other user-contributed LAMMPS source files. They need to create a class that is inside the LAMMPS namespace. If the file is for one of the USER packages, including USER-MISC, then we are not as picky about the coding style (see above). I.e. the files do not need to be in the same stylistic format and syntax as other LAMMPS files, though that would be nice for developers as well as users who try to read your code.
+* You **must** also create or extend a documentation file for each new command or style you are adding to LAMMPS. For simplicity and convenience, the documentation of groups of closely related commands or styles may be combined into a single file. This will be one file for a single-file feature. For a package, it might be several files. These are simple text files with a specific markup language, that are then auto-converted to HTML and PDF. The tools for this conversion are included in the source distribution, and the translation can be as simple as doing "make html pdf" in the doc folder. Thus the documentation source files must be in the same format and style as other `<name>.txt` files in the lammps/doc/src directory for similar commands and styles; use one or more of them as a starting point. A description of the markup can also be found in `lammps/doc/utils/txt2html/README.html` As appropriate, the text files can include links to equations (see doc/Eqs/*.tex for examples, we auto-create the associated JPG files), or figures (see doc/JPG for examples), or even additional PDF files with further details (see doc/PDF for examples). The doc page should also include literature citations as appropriate; see the bottom of doc/fix_nh.txt for examples and the earlier part of the same file for how to format the cite itself. The "Restrictions" section of the doc page should indicate that your command is only available if LAMMPS is built with the appropriate USER-MISC or USER-FOO package. See other user package doc files for examples of how to do this. The prerequisite for building the HTML format files are Python 3.x and virtualenv, the requirement for generating the PDF format manual is the htmldoc software. Please run at least "make html" and carefully inspect and proofread the resulting HTML format doc page before submitting your code.
+* For a new package (or even a single command) you should include one or more example scripts demonstrating its use. These should run in no more than a couple minutes, even on a single processor, and not require large data files as input. See directories under examples/USER for examples of input scripts other users provided for their packages. These example inputs are also required for validating memory accesses and testing for memory leaks with valgrind
+* If there is a paper of yours describing your feature (either the algorithm/science behind the feature itself, or its initial usage, or its implementation in LAMMPS), you can add the citation to the *.cpp source file. See src/USER-EFF/atom_vec_electron.cpp for an example. A LaTeX citation is stored in a variable at the top of the file and a single line of code that references the variable is added to the constructor of the class. Whenever a user invokes your feature from their input script, this will cause LAMMPS to output the citation to a log.cite file and prompt the user to examine the file. Note that you should only use this for a paper you or your group authored. E.g. adding a cite in the code for a paper by Nose and Hoover if you write a fix that implements their integrator is not the intended usage. That kind of citation should just be in the doc page you provide.
+
+Finally, as a general rule-of-thumb, the more clear and self-explanatory you make your documentation and README files, and the easier you make it for people to get started, e.g. by providing example scripts, the more likely it is that users will try out your new feature.
+
+If the new features/files are broadly useful we may add them as core files to LAMMPS or as part of a standard package. Else we will add them as a user-contributed file or package. Examples of user packages are in src sub-directories that start with USER. The USER-MISC package is simply a collection of (mostly) unrelated single files, which is the simplest way to have your contribution quickly added to the LAMMPS distribution. You can see a list of the both standard and user packages by typing "make package" in the LAMMPS src directory.
+
+Note that by providing us files to release, you are agreeing to make them open-source, i.e. we can release them under the terms of the GPL, used as a license for the rest of LAMMPS. See Section 1.4 for details.
+
+With user packages and files, all we are really providing (aside from the fame and fortune that accompanies having your name in the source code and on the Authors page of the LAMMPS WWW site), is a means for you to distribute your work to the LAMMPS user community, and a mechanism for others to easily try out your new feature. This may help you find bugs or make contact with new collaborators. Note that you are also implicitly agreeing to support your code which means answer questions, fix bugs, and maintain it if LAMMPS changes in some way that breaks it (an unusual event).
+
+To be able to submit an issue on GitHub, you have to register for an account (for GitHub in general). If you do not want to do that, or have other reservations or difficulties to submit a pull request, you can - as an alternative - contact one or more of the core LAMMPS developers and ask if one of them would be interested in manually merging your code into LAMMPS and send them your source code. Since the effort to merge a pull request is a small fraction of the effort of integrating source code manually (which would usually be done by converting the contribution into a pull request), your chances to have your new code included quickly are the best with a pull request.
+
+If you prefer to submit patches or full files, you should first make certain, that your code works correctly with the latest patch-level version of LAMMPS and contains all bug fixes from it. Then create a gzipped tar file of all changed or added files or a corresponding patch file using 'diff -u' or 'diff -c' and compress it with gzip. Please only use gzip compression, as this works well on all platforms.
+
+## GitHub Workflows
+
+This section briefly summarizes the steps that will happen **after** you have submitted either an issue or a pull request on the LAMMPS GitHub project page. 
+
+### Issues
+
+After submitting an issue, one or more of the LAMMPS developers will review it and categorize it by assigning labels. Confirmed bug reports will be labeled `bug`; if the bug report also contains a suggestion for how to fix it, it will be labeled `bugfix`; if the issue is a feature request, it will be labeled `enhancement`. Other labels may be attached as well, depending on which parts of the LAMMPS code are affected. If the assessment is, that the issue does not warrant any changes, the `wontfix` label will be applied and if the submission is incorrect or something that should not be submitted as an issue, the `invalid` label will be applied. In both of the last two cases, the issue will then be closed without further action.
+
+For feature requests, what happens next is that developers may comment on the viability or relevance of the request, discuss and make suggestions for how to implement it. If a LAMMPS developer or user is planning to implement the feature, the issue will be assigned to that developer. For developers, that are not yet listed as LAMMPS project collaborators, they will receive an invitation to be added to the LAMMPS project as a collaborator so they can get assigned. If the requested feature or enhancement is implemented, it will usually be submitted as a pull request, which will contain a reference to the issue number. And once the pull request is reviewed and accepted for inclusion into LAMMPS, the issue will be closed. For details on how pull requests are processed, please see below.
+
+For bug reports, the next step is that one of the core LAMMPS developers will self-assign to the issue and try to confirm the bug. If confirmed, the `bug` label and potentially other labels are added to classify the issue and its impact to LAMMPS. Before confirming, further questions may be asked or requests for providing additional input files or details about the steps required to reproduce the issue. Any bugfix is likely to be submitted as a pull request (more about that below) and since most bugs require only local changes, the bugfix may be included in a pull request specifically set up to collect such local bugfixes or small enhancements. Once the bugfix is included in the master branch, the issue will be closed.
+
+### Pull Requests
+
+For submitting pull requests, there is a [detailed tutorial](http://lammps.sandia.gov/doc/tutorial_github.html) in the LAMMPS manual. Thus only a brief breakdown of the steps is presented here.
+Immediately after the submission, the LAMMPS continuing integration server at ci.lammps.org will download your submitted branch and perform a simple compilation test, i.e. will test whether your submitted code can be compiled under various conditions. It will also do a check on whether your included documentation translates cleanly. Whether these tests are successful or fail will be recorded. If a test fails, please inspect the corresponding output on the CI server and take the necessary steps, if needed, so that the code can compile cleanly again. The test will be re-run each the pull request is updated with a push to the remote branch on GitHub.
+Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you are not yet registered as a LAMMPS collaborator, you will receive an invitation for that.
+You may also receive comments and suggestions on the overall submission or specific details. If permitted, additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
+The LAMMPS developer may then decide to assign the pull request to another developer (e.g. when that developer is more knowledgeable about the submitted feature or enhancement or has written the modified code). It may also happen, that additional developers are requested to provide a review and approve the changes. For submissions, that may change the general behavior of LAMMPS, or where a possibility of unwanted side effects exists, additional tests may be requested by the assigned developer.
+If the assigned developer is satisfied and considers the submission ready for inclusion into LAMMPS, the pull request will be assigned to the LAMMPS lead developer, Steve Plimpton (@sjplimp), who will then have the final decision on whether the submission will be included, additional changes are required or it will be ultimately rejected. After the pull request is merged, you may delete the pull request branch in your personal LAMMPS fork.
+Since the learning curve for git is quite steep for efficiently managing remote repositories, local and remote branches, pull requests and more, do not hesitate to ask questions, if you are not sure about how to do certain steps that are asked of you. Even if the changes asked of you do not make sense to you, they may be important for the LAMMPS developers. Please also note, that these all are guidelines and not set in stone.

 Packages that require extra libraries :h5,link(start_3_3)
 
-A few of the standard and user packages require additional auxiliary
-libraries.  Many of them are provided with LAMMPS, in which case they
-must be compiled first, before LAMMPS is built, if you wish to include
-that package.  If you get a LAMMPS build error about a missing
-library, this is likely the reason.  See the
-"Section 4"_Section_packages.html doc page for a list of
-packages that have these kinds of auxiliary libraries.
+A few of the standard and user packages require extra libraries.  See
+"Section 4"_Section_packages.html for two tables of packages which
+indicate which ones require libraries.  For each such package, the
+Section 4 doc page gives details on how to build the extra library,
+including how to download it if necessary.  The basic ideas are
+summarized here.
 
-The lib directory in the distribution has sub-directories with package
-names that correspond to the needed auxiliary libs, e.g. lib/gpu.
-Each sub-directory has a README file that gives more details.  Code
-for most of the auxiliary libraries is included in that directory.
-Examples are the USER-ATC and MEAM packages.
+[System libraries:]
 
-A few of the lib sub-directories do not include code, but do include
-instructions (and sometimes scripts) that automate the process of
-downloading the auxiliary library and installing it so LAMMPS can link
-to it.  Examples are the KIM, VORONOI, USER-MOLFILE, and USER-SMD
-packages.
+Packages in the tables "Section 4"_Section_packages.html with a "sys"
+in the last column link to system libraries that typically already
+exist on your machine.  E.g. the python package links to a system
+Python library.  If your machine does not have the required library,
+you will have to download and install it on your machine, in either
+the system or user space.
 
-The lib/python directory (for the PYTHON package) contains only a
-choice of Makefile.lammps.* files.  This is because no auxiliary code
-or libraries are needed, only the Python library and other system libs
-that should already available on your system.  However, the
-Makefile.lammps file is needed to tell LAMMPS which libs to use and
-where to find them.
+[Internal libraries:]
 
-For libraries with provided code, the sub-directory README file
-(e.g. lib/atc/README) has instructions on how to build that library.
-This information is also summarized in "Section
-4"_Section_packages.html.  Typically this is done by typing
-something like:
+Packages in the tables "Section 4"_Section_packages.html with an "int"
+in the last column link to internal libraries whose source code is
+included with LAMMPS, in the lib/name directory where name is the
+package name.  You must first build the library in that directory
+before building LAMMPS with that package installed.  E.g. the gpu
+package links to a library you build in the lib/gpu dir.  You can
+often do the build in one step by typing "make lib-name args=..."
+from the src dir, with appropriate arguments.  You can leave off the
+args to see a help message.  See "Section 4"_Section_packages.html for
+details for each package.
 
-make -f Makefile.g++ :pre
+[External libraries:]
 
-If one of the provided Makefiles is not appropriate for your system
-you will need to edit or add one.  Note that all the Makefiles have a
-setting for EXTRAMAKE at the top that specifies a Makefile.lammps.*
-file.
+Packages in the tables "Section 4"_Section_packages.html with an "ext"
+in the last column link to exernal libraries whose source code is not
+included with LAMMPS.  You must first download and install the library
+before building LAMMPS with that package installed.  E.g. the voronoi
+package links to the freely available "Voro++ library"_voro_home2.  You
+can often do the download/build in one step by typing "make lib-name
+args=..." from the src dir, with appropriate arguments.  You can leave
+off the args to see a help message.  See "Section
+4"_Section_packages.html for details for each package.
 
-If the library build is successful, it will produce 2 files in the lib
-directory:
+:link(voro_home2,http://math.lbl.gov/voro++)
 
-libpackage.a
-Makefile.lammps :pre
+[Possible errors:]
 
-The Makefile.lammps file will typically be a copy of one of the
-Makefile.lammps.* files in the library directory.
+There are various common errors which can occur when building extra
+libraries or when building LAMMPS with packages that require the extra
+libraries.
 
-Note that you must insure that the settings in Makefile.lammps are
-appropriate for your system.  If they are not, the LAMMPS build may
-fail.  To fix this, you can edit or create a new Makefile.lammps.*
-file for your system, and copy it to Makefile.lammps.
+If you cannot build the extra library itself successfully, you may
+need to edit or create an appropriate Makefile for your machine, e.g.
+with appropriate compiler or system settings.  Provided makefiles are
+typically in the lib/name directory.  E.g. see the Makefile.* files in
+lib/gpu.
 
-As explained in the lib/package/README files, the settings in
-Makefile.lammps are used to specify additional system libraries and
-their locations so that LAMMPS can build with the auxiliary library.
-For example, if the MEAM package is used, the auxiliary library
-consists of F90 code, built with a Fortran complier.  To link that
-library with LAMMPS (a C++ code) via whatever C++ compiler LAMMPS is
-built with, typically requires additional Fortran-to-C libraries be
-included in the link.  Another example are the BLAS and LAPACK
-libraries needed to use the USER-ATC or USER-AWPMD packages.
+The LAMMPS build often uses settings in a lib/name/Makefile.lammps
+file which either exists in the LAMMPS distribution or is created or
+copied from a lib/name/Makefile.lammps.* file when the library is
+built.  If those settings are not correct for your machine you will
+need to edit or create an appropriate Makefile.lammps file.
 
-For libraries without provided code, the sub-directory README file has
-information on where to download the library and how to build it,
-e.g. lib/voronoi/README and lib/smd/README.  The README files also
-describe how you must either (a) create soft links, via the "ln"
-command, in those directories to point to where you built or installed
-the packages, or (b) check or edit the Makefile.lammps file in the
-same directory to provide that information.
+Package-specific details for these steps are given in "Section
+4"_Section_packages.html an in README files in the lib/name
+directories.
 
-Some of the sub-directories, e.g. lib/voronoi, also have an install.py
-script which can be used to automate the process of
-downloading/building/installing the auxiliary library, and setting the
-needed soft links.  Type "python install.py" for further instructions.
+[Compiler options needed for accelerator packages:]
 
-As with the sub-directories containing library code, if the soft links
-or settings in the lib/package/Makefile.lammps files are not correct,
-the LAMMPS build will typically fail.
+Several packages contain code that is optimized for specific hardware,
+e.g. CPU, KNL, or GPU.  These are the OPT, GPU, KOKKOS, USER-INTEL,
+and USER-OMP packages.  Compiling and linking the source files in
+these accelerator packages for optimal performance requires specific
+settings in the Makefile.machine file you use.

-The src directory includes a Make.py script, written in Python, which
-can be used to automate various steps of the build process.  It is
-particularly useful for working with the accelerator packages, as well
-as other packages which require auxiliary libraries to be built.
-
-The goal of the Make.py tool is to allow any complex multi-step LAMMPS
-build to be performed as a single Make.py command.  And you can
-archive the commands, so they can be re-invoked later via the -r
-(redo) switch.  If you find some LAMMPS build procedure that can't be
-done in a single Make.py command, let the developers know, and we'll
-see if we can augment the tool.
-
-You can run Make.py from the src directory by typing either:
-
-Make.py -h
-python Make.py -h :pre
-
-which will give you help info about the tool.  For the former to work,
-you may need to edit the first line of Make.py to point to your local
-Python.  And you may need to insure the script is executable:
-
-chmod +x Make.py :pre
-
-Here are examples of build tasks you can perform with Make.py:
-
-Install/uninstall packages: Make.py -p no-lib kokkos omp intel
-Build specific auxiliary libs: Make.py -a lib-atc lib-meam
-Build libs for all installed packages: Make.py -p cuda gpu -gpu mode=double arch=31 -a lib-all
-Create a Makefile from scratch with compiler and MPI settings: Make.py -m none -cc g++ -mpi mpich -a file
-Augment Makefile.serial with settings for installed packages: Make.py -p intel -intel cpu -m serial -a file
-Add JPG and FFTW support to Makefile.mpi: Make.py -m mpi -jpg -fft fftw -a file
-Build LAMMPS with a parallel make using Makefile.mpi: Make.py -j 16 -m mpi -a exe
-Build LAMMPS and libs it needs using Makefile.serial with accelerator settings: Make.py -p gpu intel -intel cpu -a lib-all file serial :tb(s=:)

+that the results should be reproducible from run to run with the

+libraries or library settings (MPI, OpenMP, FFT). However, there

+order of operations compared to LAMMPS without acceleration:
+
+Neighbor lists can be created in a different order :ulb,l
+Bins used for sorting atoms can be oriented differently :l
+The default stencil order for PPPM is 7. By default, LAMMPS will
+calculate other PPPM parameters to fit the desired acuracy with

+
+The precision mode (described below) used with the USER-INTEL
+package can change the {accuracy} of the calculations. For the
+default {mixed} precision option, calculations between pairs or
+triplets of atoms are performed in single precision, intended to
+be within the inherent error of MD simulations. All accumulation
+is performed in double precision to prevent the error from growing

+[Examples:]

+
+[Description:]
+
+Define a computation that calculates the Common Neighborhood
+Parameter (CNP) for each atom in the group.  In solid-state systems
+the CNP is a useful measure of the local crystal structure
+around an atom and can be used to characterize whether the
+atom is part of a perfect lattice, a local defect (e.g. a dislocation
+or stacking fault), or at a surface.
+
+The value of the CNP parameter will be 0.0 for atoms not in the
+specified compute group.  Note that normally a CNP calculation should
+only be performed on single component systems.
+
+This parameter is computed using the following formula from
+"(Tsuzuki)"_#Tsuzuki2
+
+:c,image(Eqs/cnp_eq.jpg)
+
+where the index {j} goes over the {n}i nearest neighbors of atom
+{i}, and the index {k} goes over the {n}ij common nearest neighbors
+between atom {i} and atom {j}. Rik and Rjk are the vectors connecting atom
+{k} to atoms {i} and {j}.  The quantity in the double sum is computed
+for each atom.
+
+The CNP calculation is sensitive to the specified cutoff value.
+You should ensure that the appropriate nearest neighbors of an atom are
+found within the cutoff distance for the presumed crystal structure.
+E.g. 12 nearest neighbor for perfect FCC and HCP crystals, 14 nearest
+neighbors for perfect BCC crystals.  These formulas can be used to
+obtain a good cutoff distance:
+
+:c,image(Eqs/cnp_cutoff.jpg)
+
+where a is the lattice constant for the crystal structure concerned
+and in the HCP case, x = (c/a) / 1.633, where 1.633 is the ideal c/a
+for HCP crystals.
+
+Also note that since the CNP calculation in LAMMPS uses the neighbors
+of an owned atom to find the nearest neighbors of a ghost atom, the
+following relation should also be satisfied:
+
+:c,image(Eqs/cnp_cutoff2.jpg)
+
+where Rc is the cutoff distance of the potential, Rs is the skin
+distance as specified by the "neighbor"_neighbor.html command, and
+cutoff is the argument used with the compute cnp/atom command.  LAMMPS
+will issue a warning if this is not the case.
+
+The neighbor list needed to compute this quantity is constructed each
+time the calculation is performed (e.g. each time a snapshot of atoms
+is dumped).  Thus it can be inefficient to compute/dump this quantity
+too frequently or to have multiple compute/dump commands, each with a
+{cnp/atom} style.
+
+[Output info:]
+
+This compute calculates a per-atom vector, which can be accessed by
+any command that uses per-atom values from a compute as input.  See
+"Section 6.15"_Section_howto.html#howto_15 for an overview of
+LAMMPS output options.
+
+The per-atom vector values will be real positive numbers. Some typical CNP
+values:
+
+FCC lattice = 0.0
+BCC lattice = 0.0

+The keyword {special} controls whether an internal list of special

+
+The default value is {yes}.  A value of {no} cannot be used

+Note that you MUST insure the internal list is re-built after the last

-
-The style {custom/vtk} is similar to the "custom"_dump.html style but
-uses the VTK library to write data to VTK simple legacy or XML format
-depending on the filename extension specified. This can be either
-{*.vtk} for the legacy format or {*.vtp} and {*.vtu}, respectively,
-for the XML format; see the "VTK
-homepage"_http://www.vtk.org/VTK/img/file-formats.pdf for a detailed
-description of these formats.  Since this naming convention conflicts
-with the way binary output is usually specified (see below),
-"dump_modify binary"_dump_modify.html allows to set the binary
-flag for this dump style explicitly.
-
-[Description:]
-
-Dump a snapshot of atom quantities to one or more files every N
-timesteps in a format readable by the "VTK visualization
-toolkit"_http://www.vtk.org or other visualization tools that use it,
-e.g. "ParaView"_http://www.paraview.org.  The timesteps on which dump
-output is written can also be controlled by a variable; see the
-"dump_modify every"_dump_modify.html command for details.
-
-Only information for atoms in the specified group is dumped.  The
-"dump_modify thresh and region"_dump_modify.html commands can also
-alter what atoms are included; see details below.
-
-As described below, special characters ("*", "%") in the filename
-determine the kind of output.
-
-IMPORTANT NOTE: Because periodic boundary conditions are enforced only
-on timesteps when neighbor lists are rebuilt, the coordinates of an
-atom written to a dump file may be slightly outside the simulation
-box.
-
-IMPORTANT NOTE: Unless the "dump_modify sort"_dump_modify.html
-option is invoked, the lines of atom information written to dump files
-will be in an indeterminate order for each snapshot.  This is even
-true when running on a single processor, if the "atom_modify
-sort"_atom_modify.html option is on, which it is by default.  In this
-case atoms are re-ordered periodically during a simulation, due to
-spatial sorting.  It is also true when running in parallel, because
-data for a single snapshot is collected from multiple processors, each
-of which owns a subset of the atoms.
-
-For the {custom/vtk} style, sorting is off by default. See the
-"dump_modify"_dump_modify.html doc page for details.
-
-:line
-
-The dimensions of the simulation box are written to a separate file
-for each snapshot (either in legacy VTK or XML format depending on
-the format of the main dump file) with the suffix {_boundingBox}
-appended to the given dump filename.
-
-For an orthogonal simulation box this information is saved as a
-rectilinear grid (legacy .vtk or .vtr XML format).
-
-Triclinic simulation boxes (non-orthogonal) are saved as
-hexahedrons in either legacy .vtk or .vtu XML format.
-
-Style {custom/vtk} allows you to specify a list of atom attributes
-to be written to the dump file for each atom.  Possible attributes
-are listed above.  In contrast to the {custom} style, the attributes
-are rearranged to ensure correct ordering of vector components
-(except for computes and fixes - these have to be given in the right
-order) and duplicate entries are removed.
-
-You cannot specify a quantity that is not defined for a particular
-simulation - such as {q} for atom style {bond}, since that atom style
-doesn't assign charges.  Dumps occur at the very end of a timestep,
-so atom attributes will include effects due to fixes that are applied
-during the timestep.  An explanation of the possible dump custom/vtk attributes
-is given below. Since position data is required to write VTK files "x y z"
-do not have to be specified explicitly.
-
-The VTK format uses a single snapshot of the system per file, thus
-a wildcard "*" must be included in the filename, as discussed below.
-Otherwise the dump files will get overwritten with the new snapshot
-each time.
-
-:line
-
-Dumps are performed on timesteps that are a multiple of N (including
-timestep 0) and on the last timestep of a minimization if the
-minimization converges.  Note that this means a dump will not be
-performed on the initial timestep after the dump command is invoked,
-if the current timestep is not a multiple of N.  This behavior can be
-changed via the "dump_modify first"_dump_modify.html command, which
-can also be useful if the dump command is invoked after a minimization
-ended on an arbitrary timestep.  N can be changed between runs by
-using the "dump_modify every"_dump_modify.html command.
-The "dump_modify every"_dump_modify.html command
-also allows a variable to be used to determine the sequence of
-timesteps on which dump files are written.  In this mode a dump on the
-first timestep of a run will also not be written unless the
-"dump_modify first"_dump_modify.html command is used.
-
-Dump filenames can contain two wildcard characters.  If a "*"
-character appears in the filename, then one file per snapshot is
-written and the "*" character is replaced with the timestep value.
-For example, tmp.dump*.vtk becomes tmp.dump0.vtk, tmp.dump10000.vtk,
-tmp.dump20000.vtk, etc.  Note that the "dump_modify pad"_dump_modify.html
-command can be used to insure all timestep numbers are the same length
-(e.g. 00010), which can make it easier to read a series of dump files
-in order with some post-processing tools.
-
-If a "%" character appears in the filename, then each of P processors
-writes a portion of the dump file, and the "%" character is replaced
-with the processor ID from 0 to P-1 preceded by an underscore character.
-For example, tmp.dump%.vtp becomes tmp.dump_0.vtp, tmp.dump_1.vtp, ...
-tmp.dump_P-1.vtp, etc.  This creates smaller files and can be a fast
-mode of output on parallel machines that support parallel I/O for output.
-
-By default, P = the number of processors meaning one file per
-processor, but P can be set to a smaller value via the {nfile} or
-{fileper} keywords of the "dump_modify"_dump_modify.html command.
-These options can be the most efficient way of writing out dump files
-when running on large numbers of processors.
-
-For the legacy VTK format "%" is ignored and P = 1, i.e., only
-processor 0 does write files.
-
-Note that using the "*" and "%" characters together can produce a
-large number of small dump files!
-
-If {dump_modify binary} is used, the dump file (or files, if "*" or
-"%" is also used) is written in binary format.  A binary dump file
-will be about the same size as a text version, but will typically
-write out much faster.
-
-:line
-
-This section explains the atom attributes that can be specified as
-part of the {custom/vtk} style.
-
-The {id}, {mol}, {proc}, {procp1}, {type}, {element}, {mass}, {vx},
-{vy}, {vz}, {fx}, {fy}, {fz}, {q} attributes are self-explanatory.
-
-{Id} is the atom ID.  {Mol} is the molecule ID, included in the data
-file for molecular systems.  {Proc} is the ID of the processor (0 to
-Nprocs-1) that currently owns the atom.  {Procp1} is the proc ID+1,
-which can be convenient in place of a {type} attribute (1 to Ntypes)
-for coloring atoms in a visualization program.  {Type} is the atom
-type (1 to Ntypes).  {Element} is typically the chemical name of an
-element, which you must assign to each type via the "dump_modify
-element"_dump_modify.html command.  More generally, it can be any
-string you wish to associated with an atom type.  {Mass} is the atom
-mass.  {Vx}, {vy}, {vz}, {fx}, {fy}, {fz}, and {q} are components of
-atom velocity and force and atomic charge.
-
-There are several options for outputting atom coordinates.  The {x},
-{y}, {z} attributes write atom coordinates "unscaled", in the
-appropriate distance "units"_units.html (Angstroms, sigma, etc).  Use
-{xs}, {ys}, {zs} if you want the coordinates "scaled" to the box size,
-so that each value is 0.0 to 1.0.  If the simulation box is triclinic
-(tilted), then all atom coords will still be between 0.0 and 1.0.
-I.e. actual unscaled (x,y,z) = xs*A + ys*B + zs*C, where (A,B,C) are
-the non-orthogonal vectors of the simulation box edges, as discussed
-in "Section 6.12"_Section_howto.html#howto_12.
-
-Use {xu}, {yu}, {zu} if you want the coordinates "unwrapped" by the
-image flags for each atom.  Unwrapped means that if the atom has
-passed thru a periodic boundary one or more times, the value is
-printed for what the coordinate would be if it had not been wrapped
-back into the periodic box.  Note that using {xu}, {yu}, {zu} means
-that the coordinate values may be far outside the box bounds printed
-with the snapshot.  Using {xsu}, {ysu}, {zsu} is similar to using
-{xu}, {yu}, {zu}, except that the unwrapped coordinates are scaled by
-the box size. Atoms that have passed through a periodic boundary will
-have the corresponding coordinate increased or decreased by 1.0.
-
-The image flags can be printed directly using the {ix}, {iy}, {iz}
-attributes.  For periodic dimensions, they specify which image of the
-simulation box the atom is considered to be in.  An image of 0 means
-it is inside the box as defined.  A value of 2 means add 2 box lengths
-to get the true value.  A value of -1 means subtract 1 box length to
-get the true value.  LAMMPS updates these flags as atoms cross
-periodic boundaries during the simulation.
-
-The {mux}, {muy}, {muz} attributes are specific to dipolar systems
-defined with an atom style of {dipole}.  They give the orientation of
-the atom's point dipole moment.  The {mu} attribute gives the
-magnitude of the atom's dipole moment.
-
-The {radius} and {diameter} attributes are specific to spherical
-particles that have a finite size, such as those defined with an atom
-style of {sphere}.
-
-The {omegax}, {omegay}, and {omegaz} attributes are specific to
-finite-size spherical particles that have an angular velocity.  Only
-certain atom styles, such as {sphere} define this quantity.
-
-The {angmomx}, {angmomy}, and {angmomz} attributes are specific to
-finite-size aspherical particles that have an angular momentum.  Only
-the {ellipsoid} atom style defines this quantity.
-
-The {tqx}, {tqy}, {tqz} attributes are for finite-size particles that
-can sustain a rotational torque due to interactions with other
-particles.
-
-The {c_ID} and {c_ID\[I\]} attributes allow per-atom vectors or arrays
-calculated by a "compute"_compute.html to be output.  The ID in the
-attribute should be replaced by the actual ID of the compute that has
-been defined previously in the input script.  See the
-"compute"_compute.html command for details.  There are computes for
-calculating the per-atom energy, stress, centro-symmetry parameter,
-and coordination number of individual atoms.
-
-Note that computes which calculate global or local quantities, as
-opposed to per-atom quantities, cannot be output in a dump custom/vtk
-command.  Instead, global quantities can be output by the
-"thermo_style custom"_thermo_style.html command, and local quantities
-can be output by the dump local command.
-
-If {c_ID} is used as a attribute, then the per-atom vector calculated
-by the compute is printed.  If {c_ID\[I\]} is used, then I must be in
-the range from 1-M, which will print the Ith column of the per-atom
-array with M columns calculated by the compute.  See the discussion
-above for how I can be specified with a wildcard asterisk to
-effectively specify multiple values.
-
-The {f_ID} and {f_ID\[I\]} attributes allow vector or array per-atom
-quantities calculated by a "fix"_fix.html to be output.  The ID in the
-attribute should be replaced by the actual ID of the fix that has been
-defined previously in the input script.  The "fix
-ave/atom"_fix_ave_atom.html command is one that calculates per-atom
-quantities.  Since it can time-average per-atom quantities produced by
-any "compute"_compute.html, "fix"_fix.html, or atom-style
-"variable"_variable.html, this allows those time-averaged results to
-be written to a dump file.
-
-If {f_ID} is used as a attribute, then the per-atom vector calculated
-by the fix is printed.  If {f_ID\[I\]} is used, then I must be in the
-range from 1-M, which will print the Ith column of the per-atom array
-with M columns calculated by the fix.  See the discussion above for
-how I can be specified with a wildcard asterisk to effectively specify
-multiple values.
-
-The {v_name} attribute allows per-atom vectors calculated by a
-"variable"_variable.html to be output.  The name in the attribute
-should be replaced by the actual name of the variable that has been
-defined previously in the input script.  Only an atom-style variable
-can be referenced, since it is the only style that generates per-atom
-values.  Variables of style {atom} can reference individual atom
-attributes, per-atom atom attributes, thermodynamic keywords, or
-invoke other computes, fixes, or variables when they are evaluated, so
-this is a very general means of creating quantities to output to a
-dump file.
-
-The {d_name} and {i_name} attributes allow to output custom per atom
-floating point or integer properties that are managed by
-"fix property/atom"_fix_property_atom.html.
-
-See "Section 10"_Section_modify.html of the manual for information
-on how to add new compute and fix styles to LAMMPS to calculate
-per-atom quantities which could then be output into dump files.

+[Description:]
+
+Dump a snapshot of atom coordinates every N timesteps in Amber-style
+NetCDF file format.  NetCDF files are binary, portable and
+self-describing.  This dump style will write only one file on the root
+node.  The dump style {netcdf} uses the "standard NetCDF
+library"_netcdf-home.  All data is collected on one processor and then
+written to the dump file.  Dump style {netcdf/mpiio} uses the
+"parallel NetCDF library"_pnetcdf-home and MPI-IO to write to the dump
+file in parallel; it has better performance on a larger number of
+processors.  Note that style {netcdf} outputs all atoms sorted by atom
+tag while style {netcdf/mpiio} outputs atoms in order of their MPI
+rank.
+
+NetCDF files can be directly visualized via the following tools:
+
+Ovito (http://www.ovito.org/). Ovito supports the AMBER convention and
+all extensions of this dump style. :ule,b
+
+VMD (http://www.ks.uiuc.edu/Research/vmd/). :l
+
+AtomEye (http://www.libatoms.org/). The libAtoms version of AtomEye
+contains a NetCDF reader that is not present in the standard
+distribution of AtomEye. :l,ule
+
+In addition to per-atom data, "thermo"_thermo.html data can be included in the
+dump file. The data included in the dump file is identical to the data specified
+by "thermo_style"_thermo_style.html.

+
+[Description:]
+
+Dump a snapshot of atom quantities to one or more files every N
+timesteps in a format readable by the "VTK visualization
+toolkit"_http://www.vtk.org or other visualization tools that use it,
+e.g. "ParaView"_http://www.paraview.org.  The timesteps on which dump
+output is written can also be controlled by a variable; see the
+"dump_modify every"_dump_modify.html command for details.
+
+This dump style is similar to "dump_style custom"_dump.html but uses
+the VTK library to write data to VTK simple legacy or XML format
+depending on the filename extension specified for the dump file.  This
+can be either {*.vtk} for the legacy format or {*.vtp} and {*.vtu},
+respectively, for XML format; see the "VTK
+homepage"_http://www.vtk.org/VTK/img/file-formats.pdf for a detailed
+description of these formats.  Since this naming convention conflicts
+with the way binary output is usually specified (see below), the
+"dump_modify binary"_dump_modify.html command allows setting of a
+binary option for this dump style explicitly.
+
+Only information for atoms in the specified group is dumped.  The
+"dump_modify thresh and region"_dump_modify.html commands can also
+alter what atoms are included; see details below.
+
+As described below, special characters ("*", "%") in the filename
+determine the kind of output.
+
+IMPORTANT NOTE: Because periodic boundary conditions are enforced only
+on timesteps when neighbor lists are rebuilt, the coordinates of an
+atom written to a dump file may be slightly outside the simulation
+box.
+
+IMPORTANT NOTE: Unless the "dump_modify sort"_dump_modify.html option
+is invoked, the lines of atom information written to dump files will
+be in an indeterminate order for each snapshot.  This is even true
+when running on a single processor, if the "atom_modify
+sort"_atom_modify.html option is on, which it is by default.  In this
+case atoms are re-ordered periodically during a simulation, due to
+spatial sorting.  It is also true when running in parallel, because
+data for a single snapshot is collected from multiple processors, each
+of which owns a subset of the atoms.
+
+For the {vtk} style, sorting is off by default. See the
+"dump_modify"_dump_modify.html doc page for details.
+
+:line
+
+The dimensions of the simulation box are written to a separate file
+for each snapshot (either in legacy VTK or XML format depending on the
+format of the main dump file) with the suffix {_boundingBox} appended
+to the given dump filename.
+
+For an orthogonal simulation box this information is saved as a
+rectilinear grid (legacy .vtk or .vtr XML format).
+
+Triclinic simulation boxes (non-orthogonal) are saved as
+hexahedrons in either legacy .vtk or .vtu XML format.
+
+Style {vtk} allows you to specify a list of atom attributes to be
+written to the dump file for each atom.  The list of possible attributes
+is the same as for the "dump_style custom"_dump.html command; see
+its doc page for a listing and an explanation of each attribute.
+
+NOTE: Since position data is required to write VTK files the atom
+attributes "x y z" do not have to be specified explicitly; they will
+be included in the dump file regardless.  Also, in contrast to the
+{custom} style, the specified {vtk} attributes are rearranged to
+ensure correct ordering of vector components (except for computes and
+fixes - these have to be given in the right order) and duplicate
+entries are removed.
+
+The VTK format uses a single snapshot of the system per file, thus
+a wildcard "*" must be included in the filename, as discussed below.
+Otherwise the dump files will get overwritten with the new snapshot
+each time.
+
+:line
+
+Dumps are performed on timesteps that are a multiple of N (including
+timestep 0) and on the last timestep of a minimization if the
+minimization converges.  Note that this means a dump will not be
+performed on the initial timestep after the dump command is invoked,
+if the current timestep is not a multiple of N.  This behavior can be
+changed via the "dump_modify first"_dump_modify.html command, which
+can also be useful if the dump command is invoked after a minimization
+ended on an arbitrary timestep.  N can be changed between runs by
+using the "dump_modify every"_dump_modify.html command.
+The "dump_modify every"_dump_modify.html command
+also allows a variable to be used to determine the sequence of
+timesteps on which dump files are written.  In this mode a dump on the
+first timestep of a run will also not be written unless the
+"dump_modify first"_dump_modify.html command is used.
+
+Dump filenames can contain two wildcard characters.  If a "*"
+character appears in the filename, then one file per snapshot is
+written and the "*" character is replaced with the timestep value.
+For example, tmp.dump*.vtk becomes tmp.dump0.vtk, tmp.dump10000.vtk,
+tmp.dump20000.vtk, etc.  Note that the "dump_modify pad"_dump_modify.html
+command can be used to insure all timestep numbers are the same length
+(e.g. 00010), which can make it easier to read a series of dump files
+in order with some post-processing tools.
+
+If a "%" character appears in the filename, then each of P processors
+writes a portion of the dump file, and the "%" character is replaced
+with the processor ID from 0 to P-1 preceded by an underscore character.
+For example, tmp.dump%.vtp becomes tmp.dump_0.vtp, tmp.dump_1.vtp, ...
+tmp.dump_P-1.vtp, etc.  This creates smaller files and can be a fast
+mode of output on parallel machines that support parallel I/O for output.
+
+By default, P = the number of processors meaning one file per
+processor, but P can be set to a smaller value via the {nfile} or
+{fileper} keywords of the "dump_modify"_dump_modify.html command.
+These options can be the most efficient way of writing out dump files
+when running on large numbers of processors.
+
+For the legacy VTK format "%" is ignored and P = 1, i.e., only
+processor 0 does write files.
+
+Note that using the "*" and "%" characters together can produce a
+large number of small dump files!
+
+If {dump_modify binary} is used, the dump file (or files, if "*" or
+"%" is also used) is written in binary format.  A binary dump file
+will be about the same size as a text version, but will typically
+write out much faster.

+The fix neb command must be used with the "neb" command and defines

+divided in two stages. In the first stage n replicas are relaxed
+toward a MEP until convergence.  In the second stage, the climbing

+replica having the highest energy relaxes toward the saddle point
+(i.e. the point of highest energy along the MEP), and a second
+relaxation is performed.
 
-Only the N atoms in the fix group experience inter-replica forces.
-Atoms in the two end-point replicas do not experience these forces,
-but those in intermediate replicas do.  During the initial stage of

+A key purpose of the nudging forces is to keep the replicas equally
+spaced.  During the NEB calculation, the 3N-length vector of
+interatomic force Fi = -Grad(V) for each replica I is altered.  For
+all intermediate replicas (i.e. for 1 < I < N, except the climbing
+replica) the force vector becomes:
 
-Fi = -Grad(V) + (Grad(V) dot That) That + Kspring (| Ri+i - Ri | - | Ri - Ri-1 |) That :pre
+Fi = -Grad(V) + (Grad(V) dot T') T' + Fnudge_parallel + Fnudge_perp :pre
 
-Ri are the atomic coordinates of replica I; Ri-1 and Ri+1 are the
-coordinates of its neighbor replicas.  That (t with a hat over it) is
-the unit "tangent" vector for replica I which is a function of Ri,
+T' is the unit "tangent" vector for replica I and is a function of Ri,
 Ri-1, Ri+1, and the potential energy of the 3 replicas; it points
 roughly in the direction of (Ri+i - Ri-1); see the

+"(Henkelman1)"_#Henkelman1 paper for details.  Ri are the atomic
+coordinates of replica I; Ri-1 and Ri+1 are the coordinates of its
+neighbor replicas.  The term (Grad(V) dot T') is used to remove the
+component of the gradient parallel to the path which would tend to
+distribute the replica unevenly along the path.  Fnudge_parallel is an
+artificial nudging force which is applied only in the tangent
+direction and which maintains the equal spacing between replicas (see
+below for more information).  Fnudge_perp is an optional artificial
+spring which is applied in a direction perpendicular to the tangent
+direction and which prevent the paths from forming acute kinks (see
+below for more information).
 
-The first two terms in the above equation are the component of the
-interatomic forces perpendicular to the tangent vector.  The last term
-is a spring force between replica I and its neighbors, parallel to the
-tangent vector direction with the specified spring constant {Kspring}.
+In the second stage of the NEB calculation, the interatomic force Fi
+for the climbing replica (the replica of highest energy after the
+first stage) is changed to:
 
-The effect of the first two terms is to push the atoms of each replica
-toward the minimum energy path (MEP) of conformational states that
-transition over the energy barrier.  The MEP for an energy barrier is
-defined as a sequence of 3N-dimensional states which cross the barrier
-at its saddle point, each of which has a potential energy gradient
-parallel to the MEP itself.
+Fi = -Grad(V) + 2 (Grad(V) dot T') T' :pre
 
-The effect of the last term is to push each replica away from its two
-neighbors in a direction along the MEP, so that the final set of
-states are equidistant from each other.
+and the relaxation procedure is continued to a new converged MEP.
 
-During the second stage of NEB, the forces on the N atoms in the
-replica nearest the top of the energy barrier are altered so that it

+The keyword {parallel} specifies how the parallel nudging force is
+computed.  With a value of {neigh}, the parallel nudging force is

+intermediate replica with the previous and the next image:
 
-The inter-replica forces for the other replicas are unchanged from the
-first equation.
+Fnudge_parallel = {Kspring} * (|Ri+1 - Ri| - |Ri - Ri-1|) :pre
+
+Note that in this case the specified {Kspring) is in force/distance

+
+With a value of {ideal}, the spring force is computed as suggested in

+
+Fnudge_parallel = -{Kspring} * (RD-RDideal) / (2 * meanDist) :pre
+
+where RD is the "reaction coordinate" see "neb"_neb.html section, and
+RDideal is the ideal RD for which all the images are equally spaced.
+I.e. RDideal = (I-1)*meanDist when the climbing replica is off, where
+I is the replica number).  The meanDist is the average distance
+between replicas.  Note that in this case the specified {Kspring) is
+in force units.
+
+Note that the {ideal} form of nudging can often be more effective at
+keeping the replicas equally spaced.
+
+:line
+
+The keyword {perp} specifies if and how a perpendicual nudging force
+is computed.  It adds a spring force perpendicular to the path in
+order to prevent the path from becoming too kinky.  It can
+significantly improve the convergence of the NEB calculation when the
+resolution is poor.  I.e. when few replicas are used; see
+"(Maras)"_#Maras1 for details.
+
+The perpendicular spring force is given by
+
+Fnudge_perp = {Kspring2} * F(Ri-1,Ri,Ri+1) (Ri+1 + Ri-1 - 2 Ri) :pre
+
+where {Kspring2} is the specified value.  F(Ri-1 Ri R+1) is a smooth
+scalar function of the angle Ri-1 Ri Ri+1.  It is equal to 0.0 when
+the path is straight and is equal to 1 when the angle Ri-1 Ri Ri+1 is
+acute.  F(Ri-1 Ri R+1) is defined in "(Jonsson)"_#Jonsson.
+
+If {Kspring2} is set to 0.0 (the default) then no perpendicular spring
+force is added.
+
+:line
+
+By default, no additional forces act on the first and last replicas
+during the NEB relaxation, so these replicas simply relax toward their
+respective local minima.  By using the key word {end}, additional
+forces can be applied to the first and/or last replicas, to enable
+them to relax toward a MEP while constraining their energy.
+
+The interatomic force Fi for the specified replica becomes:
+
+Fi = -Grad(V) + (Grad(V) dot T' + (E-ETarget)*Kspring3) T',  {when} Grad(V) dot T' < 0
+Fi = -Grad(V) + (Grad(V) dot T' + (ETarget- E)*Kspring3) T', {when} Grad(V) dot T' > 0
+:pre
+
+where E is the current energy of the replica and ETarget is the target
+energy.  The "spring" constant on the difference in energies is the
+specified {Kspring3} value.
+
+When {estyle} is specified as {first}, the force is applied to the
+first replica.  When {estyle} is specified as {last}, the force is
+applied to the last replica.  Note that the {end} keyword can be used
+twice to add forces to both the first and last replicas.
+
+For both these {estyle} settings, the target energy {ETarget} is set
+to the initial energy of the replica (at the start of the NEB
+calculation).
+
+If the {estyle} is specified as {last/efirst} or {last/efirst/middle},
+force is applied to the last replica, but the target energy {ETarget}
+is continuously set to the energy of the first replica, as it evolves
+during the NEB relaxation.
+
+The difference between these two {estyle} options is as follows.  When
+{estyle} is specified as {last/efirst}, no change is made to the
+inter-replica force applied to the intermediate replicas (neither
+first or last).  If the initial path is too far from the MEP, an
+intermediate repilica may relax "faster" and reach a lower energy than
+the last replica.  In this case the intermediate replica will be
+relaxing toward its own local minima.  This behavior can be prevented
+by specifying {estyle} as {last/efirst/middle} which will alter the
+inter-replica force applied to intermediate replicas by removing the
+contribution of the gradient to the inter-replica force.  This will
+only be done if a particular intermediate replica has a lower energy
+than the first replica.  This should effectively prevent the
+intermediate replicas from over-relaxing.
+
+After converging a NEB calculation using an {estyle} of
+{last/efirst/middle}, you should check that all intermediate replicas
+have a larger energy than the first replica. If this is not the case,
+the path is probably not a MEP.
+
+Finally, note that if the last replica converges toward a local
+minimum which has a larger energy than the energy of the first
+replica, a NEB calculation using an {estyle} of {last/efirst} or
+{last/efirst/middle} cannot reach final convergence.

+Python, functions defined in the driving Python interpreter can also
+be executed.
+
+Each callback is given a pointer object as first argument. This can be
+used to initialize an instance of the lammps Python interface, which
+gives access to the LAMMPS state from Python.
+
+IMPORTANT NOTE: While you can access the state of LAMMPS via library functions
+from these callbacks, trying to execute input script commands will in the best
+case not work or in the worst case result in undefined behavior.
