are you guys planning anything to make pdb2gmx understand the CHARMM patch
residues? We have some python scripts which generate new residues based on
the patch residues, which allows us to simulate branched molecules (e.g.
glycosylation or lignin). But that approach is very suboptimal and I think
a more general approach would be very nice.
