/* ERROR/WARNING messages:
E: NEB command before simulation box is defined
Self-explanatory.
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Cannot use NEB with a single replica
Self-explanatory.
E: Can only use NEB with 1-processor replicas
This is current restriction for NEB as implemented in LAMMPS.
E: Cannot use NEB with atom_modify sort enabled
This is current restriction for NEB implemented in LAMMPS.
E: Cannot use NEB unless atom map exists
Use the atom_modify command to create an atom map.
E: NEB requires use of fix neb
Self-explanatory.
E: NEB requires damped dynamics minimizer
Use a different minimization style.
E: Too many timesteps for NEB
You must use a number of timesteps that fit in a 32-bit integer
for NEB.
E: Too many timesteps
The cummulative timesteps must fit in a 64-bit integer.
E: Unexpected end of neb file
A read operation from the file failed.
E: Incorrect atom format in neb file
The number of fields per line is not what expected.
E: Invalid atom IDs in neb file
An ID in the file was not found in the system.
E: Cannot open gzipped file
LAMMPS was compiled without support for reading and writing gzipped
files through a pipeline to the gzip program with -DLAMMPS_GZIP.
E: Cannot open file %s
The specified file cannot be opened. Check that the path and name are
correct. If the file is a compressed file, also check that the gzip
executable can be found and run.
