Detailed discussion of errors and warnings
==========================================
Many errors or warnings are self-explanatory and thus straightforward to
resolve. However, there are also cases, where there is no single cause
and explanation, where LAMMPS can only detect symptoms of an error but
not the exact cause, or where the explanation needs to be more detailed than
what can be fit into a message printed by the program. The following are
discussions of such cases.
.. _err0001:
Unknown identifier in data file
-------------------------------
This error happens when LAMMPS encounters a line of text in an unexpected format
while reading a data file. This is most commonly cause by inconsistent header and
section data. The header section informs LAMMPS how many entries or lines are expected in the
various sections (like Atoms, Masses, Pair Coeffs, *etc.*\ ) of the data file.
If there is a mismatch, LAMMPS will either keep reading beyond the end of a section
or stop reading before the section has ended.
Such a mismatch can happen unexpectedly when the first line of the data
is *not* a comment as required by the format. That would result in
LAMMPS expecting, for instance, 0 atoms because the "atoms" header line
is treated as a comment.

The *angle* keyword uses the specified variable to change the value of
an angle coefficient over time, very similar to how the *pair* keyword
operates. The only difference is that now an angle coefficient for a
given angle type is adapted.

The point in the timestep at which atoms are assigned to a dynamic
group is after the initial stage of velocity Verlet time integration
has been performed, and before neighbor lists or forces are computed.
This is the point in the timestep where atom positions have just
changed due to the time integration, so the region criterion should be
accurate, if applied.
group is after interatomic forces have been computed, but before any
fixes which alter forces or otherwise update the system have been
invoked. This means that atom positions have been updated, neighbor
lists and ghost atoms are current, and both intermolecular and
intramolecular forces have been calculated based on the new
coordinates. Thus the region criterion, if applied, should be
accurate. Also, any computes invoked by an atom-style variable should
use updated information for that timestep, e.g. potential energy/atom
or coordination number/atom. Similarly, fixes or computes which are
invoked after that point in the timestep, should operate on the new
group of atoms.
