/* ERROR/WARNING messages:
E: Delete_atoms command before simulation box is defined
The delete_atoms 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: Cannot use delete_atoms unless atoms have IDs
Your atoms do not have IDs, so the delete_atoms command cannot be
used.
E: Could not find delete_atoms group ID
Group ID used in the delete_atoms command does not exist.
E: Could not find delete_atoms region ID
Region ID used in the delete_atoms command does not exist.
E: Delete_atoms requires a pair style be defined
This is because atom deletion within a cutoff uses a pairwise
neighbor list.
E: Delete_atoms cutoff > neighbor cutoff
Cannot delete atoms further away than a processor knows about.
