E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the

E: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
E: Pair style lj/charmmfsw/coul/charmmfsh requires atom attribute q
The atom style defined does not have these attributes.
E: Pair inner lj cutoff >= Pair outer lj cutoff
