/* 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: No matching element in ADP potential file
The ADP potential file does not contain elements that match the
requested elements.
E: Cannot open ADP potential file %s
The specified ADP potential file cannot be opened. Check that the
path and name are correct.
E: Incorrect element names in ADP potential file
The element names in the ADP file do not match those requested.
