/* ERROR/WARNING messages:

E: Read_dump command before simulation box is defined

The read_dump command cannot be used before a read_data, read_restart,
or create_box command.

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: Dump file does not contain requested snapshot

Self-explanatory.

E: Invalid dump reader style

Self-explanatory.

E: No box information in dump. You have to use 'box no'

Self-explanatory.

E: Read_dump triclinic status does not match simulation

Both the dump snapshot and the current LAMMPS simulation must
be using either an orthogonal or triclinic box.

E: Read_dump field not found in dump file

Self-explanatory.

E: Read_dump x,y,z fields do not have consistent scaling

Self-explanatory.

E: All read_dump x,y,z fields must be specified for scaled, triclinic coords

For triclinic boxes and scaled coordinates you must specify all 3 of
the x,y,z fields, else LAMMPS cannot reconstruct the unscaled
coordinates.

E: Too many total atoms

See the setting for bigint in the src/lmptype.h file.

E: Duplicate fields in read_dump command

Self-explanatory.

E: If read_dump purges it cannot replace or trim

These operations are not compatible.  See the read_dump doc
page for details.
