The quick answer would be to look at the ffgmx forcefield, and the ffgmx/Berger hybrid that can be obtained (either from Tieleman or the Gromacs website, I forget) and work out how the former was incorporated into the latter. Then replicate that for ffG43a2. Not necessarily simple or even valid, but that's MD for you.

How do I combine force fields or construct a topology. I have different topologies for the lipids and the protein ready. However combining them would probably lead to errors as I cannot include both the ffG43a2 and the ffgmx force fields in the same topology ? Thanks for the help, -Maria -- Maria G.
