/* 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: Compute rdf requires a pair style be defined or cutoff specified
UNDOCUMENTED
E: Compure rdf cutoff exceeds ghost atom range - use comm_modify cutoff command
UNDOCUMENTED
W: Compute rdf cutoff less than neighbor cutoff - forcing a needless neighbor list build
UNDOCUMENTED
U: Compute rdf requires a pair style be defined
Self-explanatory.
