/* 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 adf requires a pair style be defined or outer cutoff specified

Self-explanatory.

E: Compute adf cutoff exceeds ghost atom range - use comm_modify cutoff command

Self-explanatary.
