[gmx-users] OPLS and FEP parameters

[Maik Goette]

Hi all

I am trying to use FEP with the OPLSAA FF. I now have the following 
question:

Obviously, GROMACS is able to calculate OPLS A-Values through the atoms 
section directly from the FF-files.

Is GROMACS able to calculate the B-values (lambda=1) and the 
intermediates (Between A and B) depending on lambda for bonds, pairs, 
angles and dihedrals, or is it necessary to include all the A- and 
B-values for the perturbed atoms from the FF into the topology?

Regards
