/* 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 temp/cs used when bonds are not allowed

This compute only works on pairs of bonded particles.

E: Cannot find specified group ID for core particles

Self-explanatory.

E: Cannot find specified group ID for shell particles

Self-explanatory.

E: Compute temp/cs requires ghost atoms store velocity

Use the comm_modify vel yes command to enable this.

E: Number of core atoms != number of shell atoms

There must be a one-to-one pairing of core and shell atoms.

E: Core/shell partner atom not found

Could not find one of the atoms in the bond pair.

E: Core/shell partners were not all found

Could not find or more atoms in the bond pairs.

E: Temperature compute degrees of freedom < 0

This should not happen if you are calculating the temperature
on a valid set of atoms.
