# -------- WARNING: --------
|
||||
|
||||
This directory contains some examples of all-atom simulations using the GAFF
|
||||
force field, prepared using moltemplate.
|
||||
|
||||
This software is experimental, and the force-fields and equilbration protocols
|
||||
have not been tested carefully by me. There is no gaurantee that simulations
|
||||
prepared using moltemplate will reproduce the behavior of AmberTools/AMBER.
|
||||
|
||||
# -------- REQUEST FOR HELP: --------
|
||||
|
||||
If you notice a problem with these examples, please report it.
|
||||
Peer-review is the only way to improve this software (or any software).
|
||||
Other suggestions are also welcome!

|
||||
|
||||
|
||||
--- Charge ---
|
||||
|
||||
This software does not assign charges to each atom.
|
||||
(AmberTools can do this.)
|
||||
|
||||
For the purpose of demonstration, in the hydrocarbon examples located here,
|
||||
I am simply neglecting the partial charge of the carbon and hydrogen atoms.
|
||||
This approach is unlikely to be appropriate in most practical applications.
|
||||
|
||||
|
||||
--- Long-range electrostatics ---
|
||||
|
||||
Furthermore long-range electrostatics (kspace_style pppm) are usually disabled
|
||||
by default. (Examples containing TIP3P water are an exception to this.)
|
||||
To enable long-range coulombics, make these modifications to the
|
||||
"system.in.init" and "system.in.settings" files AFTER running moltemplate:
|
||||
(enter these commands into the bash shell)
|
||||
|
||||
echo "kspace_style pppm 0.0001" >> system.in.init
|
||||
echo "pair_style hybrid lj/charmm/coul/long 9.0 10.0" >> system.in.init
|
||||
sed -i 's/lj\/charmm\/coul\/charmm/lj\/charmm\/coul\/long/g' system.in.settings
|
||||
|
||||
|
||||
--- Improper angles ---
|
||||
|
||||
I am also uncertain whether the improper angle interactions generated by
|
||||
moltemplate are equivalent to those generated by AmberTools. (I think they are,
|
||||
but I am worried that I might have listed the atom types in the wrong order.)
|
||||
|
||||
|
||||
--- Bloated lammps input scripts ---
|
||||
--- -> slow simulations ? ---
|
||||
|
||||
As of 2013-12-01, LAMMPS input scripts prepared using moltemplate using the
|
||||
"gaff.lt" file contain the entire contents of the GAFF force-field,
|
||||
even if your simulation uses only a few of the atom types in GAFF.
|
||||
|
||||
Details:
|
||||
Moltemplate creates a file usually named "system.in.settings" containing all
|
||||
of the GAFF information. It is usually about 700kB large. This file is read
|
||||
by LAMMPS. This means that every interaction in GAFF is loaded
|
||||
into LAMMPS (for all ~72 atom types).
|
||||
This is true even if you only use a tiny subset of the atom types and bonded
|
||||
interactions defined in GAFF. Hopefully allocating the memory needed to store
|
||||
this extra information will not slow down your simulations noticably.
|
||||
|
||||
However, in case it does, the "waterTIP3P+isobutane/README_setup.sh"
|
||||
contains detailed instructions how to strip this kind of junk from
|
||||
the "system.in.settings" file.
|
||||
|
||||
(In the future I may modify moltemplate to do this automatically,
|
||||
however I may not remember to remove this warning from this file.
|
||||
Hopefully this issue will be fixed by the time you use moltemplate.)

This example is a simple simulation of 288 hexadecane molecules in a box at
|
||||
room temperature and atmospheric pressure. Please read the WARNING.TXT file.
|
||||
|
||||
-------- REQUIREMENTS: ---------
|
||||
This example requires building LAMMPS with the "USER-MISC" package.
|
||||
(because it uses dihedral_style fourier)
|
||||
To do this, type "make yes-user-misc" before compiling LAMMPS.
|
||||
http://lammps.sandia.gov/doc/Section_start.html#start_3
|
||||
|
||||
More detailed instructions on how to build LAMMPS input files and
|
||||
run a short simulation are provided in other README files:
|
||||
|
||||
step 1) to setup the LAMMPS input files, run this file:
|
||||
README_setup.sh
|
||||
|
||||
(Currently there is a bug which makes this step slow.
|
||||
I'll fix it later -Andrew 2013-10-15.)
|
||||
|
||||
step 2) to run LAMMPS, follow the instructions in this file:
|
||||
README_run.sh
|
||||
|
||||
------------ NOTE: There are two versions of this example. ----------------
|
||||
|
||||
Both examples use the same force-field parameters.
|
||||
|
||||
1)
|
||||
In this version, the force-field parameters are loaded from the "gaff.lt" file
|
||||
(located in the "common" subdirectory).
|
||||
This frees the user from the drudgery of manually specifying all of these
|
||||
force-field details for every molecule. (However, the user must be careful
|
||||
to choose @atom-type names which match AMBER GAFF conventions,
|
||||
such as the "c3" and "h1" atoms, in this example.)
|
||||
|
||||
2)
|
||||
Alternately, there is another "hexadecane" example in the "all_atom_examples"
|
||||
directory. In that example, force-field parameters are loaded from a file
|
||||
named "alkanes.lt" (instead of "gaff.lt"). The "alkanes.lt" file contains
|
||||
only the excerpts from "gaff.lt" which are relevant to the hydrocarbon
|
||||
molcules used in that example. ("gaff.lt" contains parameters for most
|
||||
small organic molecules, not just hydrocarbons.)
|
||||
In this way, by editing "alkanes.lt", the user can manually control all of the
|
||||
force-field details in the simulation. (Without feeling as though they are
|
||||
relying on some kind of mysterious "black box" to do it for them.)

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

This is an example of how to use "canned" force-fields in like GAFF in LAMMPS.
|
||||
In this example, we specify only the atom names, bond connectivity,
|
||||
(and coordinates and charge), and use moltemplate to
|
||||
load the GAFF parameters from an external file (gaff.lt)
|
||||
(...instead of specifying them explicitly in the molecule definition).
|
||||
|
||||
The simulation consists of a mixture of isobutane and water.
|
||||
Over time (less than 1 ns), the two molecules phase-separate.
|
||||
|
||||
The GAFF parameters are applied only to the isobutane molecule.
|
||||
(The water molecule paramters are defined explicitly in common/tip3p_2004.lt)
|
||||
For this to work, make sure you have defined the MOLTEMPLATE_PATH
|
||||
environment variable and set it to "common". See manual for more details.)

# rules. This would force us to add a huge list of pair_coeff commands to

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

|

This directory contains instructions for creating a a moltemplate file
|
||||
("oplsaa.lt") containing force-field definitions relevant to ethylene example.
|
||||
Create "oplsaa.lt" this way:
|
||||
|
||||
./oplsaa_moltemplate.py oplsaa_subset.txt
|
||||
|
||||
# Then move the newly created opls.lt file to the parent directory
|
||||
# (to help moltemplate find it).
|
||||
|
||||
mv oplsaa.lt ..
|
||||
|
||||
----------- GENERAL DOCUMENTATION -----------
|
||||
The "oplsaa_subset.txt" file should contain force-field information
|
||||
for a subset of the atoms in the oplsaa forcefield. This directory
|
||||
also contains the python code ("oplsaa_moltemplate.py") used to
|
||||
generate that file, as well as the full oplsaa force field file: "oplsaa.txt".
|
||||
|
||||
NOTE: THE ORIGINAL "oplsaa.txt" FILE IS LOCATED IN THE "common/opls/" DIRECTORY.
|
||||
(I deleted it here to save space.)
|
||||
|
||||
python oplsaa_moltemplate.py <force field file name>
|
||||
|
||||
First, back-up the oplsaa.txt file and then delete all the unnecessary atoms
|
||||
from the file.
|
||||
|
||||
It is ideal for you to run this on a subset of the OPLS forcefield relevant
|
||||
to your problem. (It is possible for you to generate a full OPLS force field
|
||||
moltemplate file but that demands a lot of time and generates a file that is
|
||||
on the order 100 gigabytes, which moltemplate can not read.)
|
||||
Save yourself time and energy, and make a copy of the oplsaa.txt. Then edit
|
||||
this file and delete or comment out any line beginning with the word "atom"
|
||||
which is not relevant to your problem. (However keep the rest of the file.)
|
||||
|
||||
For example:
|
||||
Let's assume this new file is called "oplsaa_subset.txt". If you were
|
||||
working with ethylene you would delete every atom except for atom 85(C=)
|
||||
and 86(H-C=) and use that as the input file for oplsaa_moltemplate.py
|
||||
|
||||
atom 85 37 CM "Alkene H2-C=" 6 12.011 3
|
||||
atom 86 36 HC "Alkene H-C=" 1 1.008 1
|
||||
|
||||
You do not need to make any other changes other than that. Then run:
|
||||
|
||||
python oplsaa_moltemplate.py oplsaa_subset.txt
|
||||
|
||||
...this will create a file named "oplsaa.lt"
|
||||
|
||||
Look over the newly created "oplsaa.lt" file. Then copy it to the "common" directory (where other force-field files like gaff.lt are located, ...or just copy it to wherever you plan to run moltemplate).
|
||||
|
||||
Then you can create molecules that refer to it using:
|
||||
|
||||
Ethylene inherits OPLSAA {
|
||||
# Definition of Ethylene molecule goes here.
|
||||
}
|
||||
|
||||
CHARGE:
|
||||
|
||||
By default, the OPLSAA force-field assigns atom charge according to atom type.
|
||||
When you run moltemplate, it will create a file named "system.in.charges",
|
||||
containing commands like:
|
||||
|
||||
set type 2 charge -0.42
|
||||
set type 3 charge 0.21
|
||||
|
||||
(This assumes your main moltemplate file is named "system.lt". If it was
|
||||
named something else, eg "polymer.lt", then the file created by moltemplate
|
||||
will be named "polymer.in.charges".)
|
||||
|
||||
Include these commands somewhere in your LAMMPS input script
|
||||
(or use the LAMMPS "include" command to load the commands in system.in.charges)
|
||||
|
||||
Note that the atom numbers (eg "2", "3") in this file will not match the
|
||||
OPLS atom numbers. (Check the output_ttree/ttree_assignments.txt file,
|
||||
created by moltemplate, to see a table of "@atom" type numbers translated
|
||||
from OPLSAA into LAMMPS.)

NOTE: This example requires the "Al99.eam.alloy" file.
|
||||
(It was not included in this directory because if its large size.)
|
||||
As of 2012-11, I was able to obtain it here:
|
||||
http://www.ctcms.nist.gov/~cbecker/Download/Al-YM/Al99.eam.alloy
|
||||
Copy it to the directory containing this README file.
|
||||

This example shows an alternative way to setup the
|
||||
aluminum crystal loading simulation described here:
|
||||
http://icme.hpc.msstate.edu/mediawiki/index.php/Uniaxial_Compression
|
||||
by Mark Tschopp and Nathan R. Rhodes
|
||||
For additional backgroumd information, please consult that web page.
|
||||
|
||||
In this example, I use moltemplate to build a "DATA" file for this system.
|
||||
(I can't think of a compelling reason to do this for simple simulations like
|
||||
this. But this approach might be useful if you want to artificially create
|
||||
unusual structures out of aluminum crystals, or mix them with other molecules.
|
||||
I created this example in response to a user request.)
|
||||
|
||||
|
||||
--- To build the system ---
|
||||
|
||||
Carry out the instructions in README_setup.sh,
|
||||
to generate the LAMMPS DATA file and input scripts you need:
|
||||
system.data, system.in.init, system.in.settings.
|
||||
(The run.in script contains references to these files.)
|
||||
|
||||
|
||||
--- To run LAMMPS, try a command like: ---
|
||||
|
||||
lmp_linux -i run.in
|
||||
|
||||
or (if you have mpi installed)
|
||||
|
||||
mpirun -np 4 lmp_linux -i run.in
|
||||
|
||||
This will create an ordinary LAMMPS dump file you can visualize with VMD
|
||||
traj.lammpstrj (See README_visualize.txt)
|
||||
|
||||
It will also create a number of other files, such as:
|
||||
dump.comp_0.cfg
|
||||
dump.comp_500.cfg
|
||||
dump.comp_20000.cfg
|
||||
Al_comp_100.def1.txt
|
||||
|
||||
The dump.comp_*.cfg files can be visualized using
|
||||
AtomEye if you have AtomEye and ImageJ installed.
|
||||
The procedure for doing this is explained in the original tutorial at:
|
||||
http://icme.hpc.msstate.edu/mediawiki/index.php/Uniaxial_Compression
|
||||
|
||||
The "Al_comp_100.def1.txt" file is a four-column text file containing:
|
||||
column 1: v_strain = (lx - v_L0)/v_L0
|
||||
column 2: -pxx/10000 (diagonal components of the stress tensor)
|

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

This example uses "ltemplify.py" to create molecule templates out
|
||||
of two different molecules in a pre-existing LAMMPS IN/DATA file.
|
||||
Then I show how to use "moltemplate.sh" to make copies of these
|
||||
molecules and to move and rotate them (creating new LAMMPS IN/DATA files).
|
||||
|
||||
Disclaimer:
|
||||
The molecules in this example are not physically realistic.
|
||||
The purpose of this example is to demonstrate ltemplify usage.
|
||||
|
||||
REQUIRED INPUT FILES
|
||||
|
||||
cnad-cnt.data cnad-cnt.in system.lt
|
||||
|
||||
cnad-cnt.data
|
||||
This is a LAMMPS data file containing the coordinates and the topology
|
||||
for a system combining the two molecules together. ltemplify will extract
|
||||
molecules from this file, one at a time.
|
||||
|
||||
cnad-cnt.in
|
||||
This file contains force-field parameters and old run settings for the system.
|
||||
(We ignore the run settings in this file.) The force-field parameters in
|
||||
the "cnad-cnt.in" file are only necessary because we are going to build
|
||||
a completely new set of simulation input files. (We are not only going to
|
||||
rotate them and duplicate the molecules.) ltemplify.py will extract the
|
||||
force field parameters from this file. This approach allows us to combine
|
||||
these molecules with other types of molecules later on.)
|
||||
|
||||
system.lt
|
||||
The "system.lt" contains the instructions what we will do with these molecules
|
||||
after ltemplify.py has converted them into .LT format. In this example
|
||||
it contains instructions for rotating and copying the two molecules,
|
||||
(It also defines the periodic boundary conditions.)
|
||||
|
||||
OUTPUT FILES
|
||||
|
||||
cnad.lt
|
||||
cnt.lt
|
||||
|
||||
These files are referenced in system.lt.
|
||||
Running moltemplate.sh on system.lt (using "moltemplate.sh system.lt")
|
||||
creates new LAMMPS data and input files:
|
||||
system.data, system.in, system.in.init, system.in.settings
|
||||
(These files are referenced in run.in.nvt.)
|
||||
|
||||
You can run a simulation from the files created by moltemplate using
|
||||
|
||||
lmp_linux -i run.in.nvt
|
||||
|
||||
NOTE: BECAUSE ALL OF THE ORIGINAL FORCE FIELD PARAMETERS WERE INTENTIONALLY
|
||||
ALTERED, THE SYSTEM WILL MOVE IN A VERY UNREALISTIC WAY WHEN SIMULATED.
|
||||
(This was done to protect the original source of the files.)
|
||||
The goal of this example is only to demonstrate how to use
|
||||
"ltemplify.py" to convert lammps input and data files into
|
||||
LT format and back again.)
|
||||
|
||||
-----------
|
||||
|
||||
Instructions:
|
||||
Run the commands (follow the instructions) in these files:
|
||||
|
||||
step 1)
|
||||
README_step1_run_ltemplify.sh
|
||||
|
||||
and then
|
||||
|
||||
step 2)
|
||||
README_step2_run_moltemplate.sh
|
||||
|
||||
step 3) OPTIONAL
|
||||
|
||||
To run a short LAMMPS simulation, you can use the "in.nvt" file, for example:
|
||||
|
||||
$LAMMPS_BINARY -i run.in.nvt
|
||||
|
||||
where "$LAMMPS_BINARY" is the name of the command you use to invoke lammps
|
||||
(such as lmp_linux, lmp_g++, lmp_mac, lmp_ubuntu, lmp_cygwin, etc...).

------- To view the trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it
|
||||
|
||||
----- Wrap the coordinates to the unit cell
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Enter:
|
||||
|
||||
DISCLAIMER: I'M NOT SURE THESE COMMANDS ARE CORRECT.
|
||||
LOOKUP "pbctools" FOR DETAILS.
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
3) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

This example is a simple simulation of 288 hexadecane molecules in a box at
|
||||
room temperature and atmospheric pressure. Please read the WARNING.TXT file.
|
||||
|
||||
-------- REQUIREMENTS: ---------
|
||||
This example requires building LAMMPS with the "USER-MISC" package.
|
||||
(because it uses dihedral_style fourier)
|
||||
To do this, type "make yes-user-misc" before compiling LAMMPS.
|
||||
http://lammps.sandia.gov/doc/Section_start.html#start_3
|
||||
|
||||
More detailed instructions on how to build LAMMPS input files and
|
||||
run a short simulation are provided in other README files:
|
||||
|
||||
step 1) to setup the LAMMPS input files, run this file:
|
||||
README_setup.sh
|
||||
|
||||
step 2) to run LAMMPS, follow the instructions in this file:
|
||||
README_run.sh
|
||||
|
||||
------------ NOTE: There are two versions of this example. ----------------
|
||||
|
||||
Both examples use the same force-field parameters.
|
||||
|
||||
1) In this directory, all of the force-field parameters are listed explicitly
|
||||
in the "alkanes.lt" file (located in the "moltemplate_files" directory).
|
||||
This allows the user to manually control all of the force-field details.
|
||||
|
||||
2) However, there is an alternate version of this example in the
|
||||
"../AMBER_force_field_examples" directory.
|
||||
In that version, the force-fields are loaded from a much larger file named
|
||||
"gaff.lt" which contains all of the parameters in the AMBER GAFF force-field
|
||||
database. The "gaff.lt" is similar to the "alkanes.lt" file except that
|
||||
it is larger (because it contains information for nearly all small organic
|
||||
molecules). It is located in a different directory (in the "common" directory).
|
||||
|
||||
Relying on "gaff.lt" frees the user from the drudgery of manually specifying
|
||||
all of these force-field details for every molecule. (However, the user must
|
||||
be careful to choose @atom-type names which match AMBER GAFF conventions,
|
||||
such as "c3" and "h1", in this example.)

|
||||
# -------- PREREQUISITES: --------
|
||||
# The 2 files "run.in.npt", and "run.in.nvt" are LAMMPS
|
||||
# input scripts which link to the input scripts and data files
|
||||
# you hopefully have created earlier with moltemplate.sh:
|
||||
# system.in.init, system.in.settings, system.data
|
||||
# If not, carry out the instructions in "README_setup.sh".
|
||||
#
|
||||
# -- Instructions: --
|
||||
# If "lmp_linux" is the name of the command you use to invoke lammps,
|
||||
# then you would run lammps on these files this way:
|
||||
|
||||
|
||||
lmp_linux -i run.in.npt # minimization and simulation at constant pressure
|
||||
lmp_linux -i run.in.nvt # minimization and simulation at constant volume
|
||||
|
||||
#(Note: The constant volume simulation lacks pressure equilibration. These are
|
||||
# completely separate simulations. The results of the constant pressure
|
||||
# simulation might be ignored when beginning the simulation at constant
|
||||
# volume. (This is because restart files in LAMMPS don't always work,
|
||||
# and I was spending a lot of time trying to convince people it was a
|
||||
# LAMMPS bug, instead of a moltemplate bug, so I disabled restart files.)
|
||||
# Read the "run.in.nvt" file to find out how to use the "read_restart"
|
||||
# command to load the results of the pressure-equilibration simulation,
|
||||
# before beginning a constant-volume run.

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

# -------- WARNING: --------
|
||||
|
||||
This software is experimental, and the force-fields and equilbration protocols
|
||||
have not been tested carefully by me. There is no gaurantee that the simulation
|
||||
will reproduce the behavior of real hexadecane molecules,
|
||||
(or even of hexadecane molecules simulated using AMBER, which should
|
||||
be using the same force-field).
|
||||
|
||||
# -------- REQUEST FOR HELP: --------
|
||||
|
||||
However, if you notice a problem with this example, please report it.
|
||||
I confess I do not have a lot of experience running all-atom simulations.
|
||||
Peer-review is the only way to improve this software (or any software).
|
||||
Other suggestions are also welcome!

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 500 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
Sometimes the solvent or membrane obscures the view of the solute.
|
||||
It can help to shift the location of the periodic boundary box
|
||||
To shift the box in the y direction (for example) do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {0.0 0.15 0.0}
|
||||
pbc box -shiftcenterrel {0.0 0.15 0.0}
|
||||
|
||||
Distances are measured in units of box-length fractions, not Angstroms.
|
||||
|
||||
Alternately if you have a solute whose atoms are all of type 1,
|
||||
then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4)
|
||||
You should check if your periodic boundary conditions are too small.
|
||||
To do that:
|
||||
select Graphics->Representations menu option
|
||||
click on the "Periodic" tab, and
|
||||
click on the "+x", "-x", "+y", "-y", "+z", "-z" checkboxes.
|
||||
|
||||
5) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)

This is a small version of a carbon-nanotube, water capillary system.
|
||||
It was inspired by this paper:
|
||||
|
||||
Laurent Joly, J. Chem. Phys. 135(21):214705 (2011)
|
||||
|
||||
-------- Requirements: -------
|
||||
To run this system at constant pressure, it might help to compile LAMMPS
|
||||
with the optional RIGID package, and use "fix rigid" on the carbon.
|
||||
(The use of fix rigid is controversial.) Running at NVT does not require this.
|
||||
------------------------------
|
||||
|
||||
Note: To investigate the behavior from that paper, it might be a good
|
||||
idea to increase the size of the water reservoir, the spacing between
|
||||
the walls, and the size of the system in the X and Y directions.
|
||||
|
||||
Note: Explicit carbon-carbon bonds:
|
||||
In the graphene and nanotube structures, I did not try to connect the
|
||||
carbon atoms together with bonds. Instead we will hold these structures
|
||||
rigid by not integrating their equations of motion.
|
||||
(If you want to simulate movement of the carbon atoms at high
|
||||
temperatures or tension, LAMMPS has 3-body/many-body LAMMPS force-fields
|
||||
available for simulating the behaviour of carbon in graphite. I know
|
||||
that you don't need to specify bonds to use these force fields. I do
|
||||
not know know if these force fields work for nanotubes or graphene.)
|
||||
|
||||
Note: Other modeling tools:
|
||||
If you need explicit bonds between carbon atoms, then you must add them
|
||||
yourself or use a different tool. Currently (2012-10-20), moltemplate does
|
||||
not generate bonds automatically. The "Nanotube Builder" and "topotools"
|
||||
plugins for for VMD can generate a nanotube with bonds in LAMMPS data
|
||||
format. You can then convert this data file to .LT format using the
|
||||
ltemplify.py utility and then import it into another .LT file and play
|
||||
with it later. (In the "cnad-cnt" example, the carbon nanotube was built
|
||||
using "Nanotube Builder" and topotools, and processed with ltemplify.py)
|
||||
|
||||
|
||||
# WARNING: THIS IS NOT A REALISTIC MODEL OF A GRAPHENE-NANOTUBE JUNCTION.
|
||||
# A real junction would be curved and deformed near the boundary,
|
||||
# (not 90 degrees) and it would not be built entirely from hexagons.
|
||||
# (This is not a problem in this example because the carbon atoms
|
||||
# are immobilized.) If you want to simulate the behavior of
|
||||
# real graphene or nanotube junctions, you must be more careful.
|
||||
# To solve this problem:
|
||||
# Moltemplate allows you to move, customize or delete individual
|
||||
# atoms near the boundary. You can move atoms by overwriting their
|
||||
# coordinates using additional write("Data Atoms") statements (after
|
||||
# the walls and tube are created). You can also change their charge.
|
||||
# Alternately, you could start with the structure provided here, and
|
||||
# relax/minimize the coordinates of the carbon atoms using LAMMPS
|
||||
# before using it in other simulations.
|
||||
# Or you could do both (customization & minimization).

------- To view a lammps trajectory in VMD --------
|
||||
|
||||
|
||||
1) Build a PSF file for use in viewing with VMD.
|
||||
|
||||
This step works with VMD 1.9 and topotools 1.2.
|
||||
(Older versions, like VMD 1.8.6, don't support this.)
|
||||
|
||||
|
||||
a) Start VMD
|
||||
b) Menu Extensions->Tk Console
|
||||
c) Enter:
|
||||
|
||||
(I assume that the the DATA file is called "system.data")
|
||||
|
||||
topo readlammpsdata system.data full
|
||||
animate write psf system.psf
|
||||
|
||||
2)
|
||||
|
||||
Later, to Load a trajectory in VMD:
|
||||
|
||||
Start VMD
|
||||
Select menu: File->New Molecule
|
||||
-Browse to select the PSF file you created above, and load it.
|
||||
(Don't close the window yet.)
|
||||
-Browse to select the trajectory file.
|
||||
If necessary, for "file type" select: "LAMMPS Trajectory"
|
||||
Load it.
|
||||
|
||||
---- A note on trajectory format: -----
|
||||
If the trajectory is a DUMP file, then make sure the it contains the
|
||||
information you need for pbctools (see below. I've been using this
|
||||
command in my LAMMPS scripts to create the trajectories:
|
||||
|
||||
dump 1 all custom 5000 DUMP_FILE.lammpstrj id mol type x y z ix iy iz
|
||||
|
||||
It's a good idea to use an atom_style which supports molecule-ID numbers
|
||||
so that you can assign a molecule-ID number to each atom. (I think this
|
||||
is needed to wrap atom coordinates without breaking molecules in half.)
|
||||
|
||||
Of course, you don't have to save your trajectories in DUMP format,
|
||||
(other formats like DCD work fine) I just mention dump files
|
||||
because these are the files I'm familiar with.
|
||||
|
||||
3) ----- Wrap the coordinates to the unit cell
|
||||
(without cutting the molecules in half)
|
||||
|
||||
a) Start VMD
|
||||
b) Load the trajectory in VMD (see above)
|
||||
c) Menu Extensions->Tk Console
|
||||
d) Try entering these commands:
|
||||
|
||||
pbc wrap -compound res -all
|
||||
pbc box
|
||||
|
||||
----- Optional ----
|
||||
To shift the box by a fraction in the x direction (for example)
|
||||
do this:
|
||||
|
||||
pbc wrap -compound res -all -shiftcenterrel {-0.50 -0.52 0.0 }
|
||||
pbc box -shiftcenterrel {-0.50 -0.52 0.0 }
|
||||
|
||||
# Alternately if you have a solute whose atoms are all of type 1,
|
||||
# then you can also try this to center the box around it:
|
||||
|
||||
pbc wrap -sel type=1 -all -centersel type=2 -center com
|
||||
|
||||
4) Optional: If you like, change the atom types in the PSF file so
|
||||
that VMD recognizes the atom types, use something like:
|
||||
|
||||
sed -e 's/ 1 1 / C C /g' < system.psf > temp1.psf
|
||||
sed -e 's/ 2 2 / H H /g' < temp1.psf > temp2.psf
|
||||
sed -e 's/ 3 3 / P P /g' < temp2.psf > system.psf
|
||||
|
||||
(If you do this, it might effect step 2 above.)
