[gmx-users] combining gromos96 (43a2) and berger lipid force field

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.

Subject: [gmx-users] combining gromos96 (43a2) and berger lipid force field

I want to use the gromos96 force field for the protein, and Tieleman's
Berger force field for the lipids. 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,
