Dear Ambers,
   I have two questions about RED:
1. How amine hydrogen should be named? Amber names are H21 and H22 for
instance...shall I keep this names ar do I have to do the same as for
2. The gaussian optimization with a RG residue with a methyl instead of
sugar takes ages when using Opt=Tight and SCF (Conver = 8). Does one
really need these tight convergence criteria?
