Hmm. Well, as you suggest, it's not any overlapping atom. I would next suggest that you have a look at the excluded atoms list, by running rdparm on the topology file and executing "printExcluded" (note: not "printExluded", as the help would suggest). See if there are any 1-2 or 1-3 pairs in there that are missing for your residue.

If you think it's the dihedrals that are responsible, one thing you could do to test that theory is to set the parameters for the particular dihedrals you're concerned about to zero, and see if you get any change in the result.

Hope that helps,
