[gmx-users] LJ parameters

[Pedro A. Lapido Loureiro]

Hello,

I wish to simulate a DPPC bilayer, using the GROMOS96 45a3 LJ parameters for the
CH2/CH3 of the lipid tails (CL2/CL3).
1)I want to scale the 1-4 interactions *-CL2/CL3 with some fudge factor.
2)I want to maintain all of the other 1-4 interactions of the GROMOS96 43a1
forcefield (ffG43a1nb.itp file).
3)If I say "generate pairs=yes" will GROMACS ignore ALL of the explicit  1-4
C6/C12 parameters under [pair types] or only those that are not written in
ffG43a1nb.itp file?

Cheers, Pedro
