/* 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: Fix property/atom mol when atom_style already has molecule attribute

Self-explanatory.

E: Fix property/atom cannot specify mol twice

Self-explanatory.

E: Fix property/atom q when atom_style already has charge attribute

Self-explanatory.

E: Fix property/atom cannot specify q twice

Self-explanatory.

E: Fix property/atom vector name already exists

The name for an integer or floating-point vector must be unique.

W: Fix property/atom mol or charge w/out ghost communication

A model typically needs these properties defined for ghost atoms.

E: Atom style was redefined after using fix property/atom

This is not allowed.

E: Incorrect %s format in data file

A section of the data file being read by fix property/atom does
not have the correct number of values per line.

E: Too few lines in %s section of data file

Self-explanatory.

E: Invalid atom ID in %s section of data file

An atom in a section of the data file being read by fix property/atom
has an invalid atom ID that is <= 0 or > the maximum existing atom ID.
