/* ERROR/WARNING messages:

E: Create_atoms command before simulation box is defined

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

E: Cannot create_atoms after reading restart file with per-atom info

The per-atom info was stored to be used when by a fix that you
may re-define.  If you add atoms before re-defining the fix, then
there will not be a correct amount of per-atom info.

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 atom type in create_atoms command

The create_box command specified the range of valid atom types.
An invalid type is being requested.

E: Create_atoms region ID does not exist

A region ID used in the create_atoms command does not exist.

E: Invalid basis setting in create_atoms command

UNDOCUMENTED

E: Cannot create atoms with undefined lattice

Must use the lattice command before using the create_atoms
command.

E: Too many total atoms

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

E: No overlap of box and region for create_atoms

Self-explanatory.
