/* ERROR/WARNING messages:
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: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
E: Cannot open AGNI potential file %s
The specified AGNI potential file cannot be opened. Check that the path
and name are correct.
E: Incorrect format in AGNI potential file
The potential file is not compatible with the AGNI pair style
implementation in this LAMMPS version.
