[gmx-users] charges for non-natural residues with gromos 53a6

[Carsten Baldauf]

dear all//
i need to parameterize a non-natural amino acid residue.
i have a problem with assigning the charges, how should i scale them? i 
can obtain quantum chemical charges from AM1 to {HF,DFT}/6-31G* and 
further, but how to include (scaling, i now where to write them) them in 
the force field?
thanks a lot//
