You need to tell us what ligand you're dealing with. A few other things to
1. The manual has a very good description of what charge groups are and how
2. If you're using PME, charge groups summing to zero or an integer is not
3. If you're going to use the Verlet cutoff scheme for the simulation, charge
groups are totally irrelevant.
