/* 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: Invalid dump xtc filename

Filenames used with the dump xtc style cannot be binary or compressed
or cause multiple files to be written.

E: Too many atoms for dump xtc

The system size must fit in a 32-bit integer to use this dump
style.

W: No automatic unit conversion to XTC file format conventions possible for units lj

This means no scaling will be performed.

E: Dump xtc requires sorting by atom ID

Use the dump_modify sort command to enable this.

E: Cannot set dump_modify flush for dump xtc

Self-explanatory.

E: Cannot use variable every setting for dump xtc

The format of this file requires snapshots at regular intervals.

E: Cannot change dump_modify every for dump xtc

The frequency of writing dump xtc snapshots cannot be changed.

E: Cannot open dump file

Self-explanatory.

E: Too big a timestep for dump xtc

The timestep must fit in a 32-bit integer to use this dump style.

E: Illegal dump_modify sfactor value (must be > 0.0)

Self-explanatory.

E: Illegal dump_modify tfactor value (must be > 0.0)

Self-explanatory.
