[gmx-users] dppc's simulation

[Chen Hao]

Dear David:
Thanks you very much for your help. By the way, what's the best parameters for pure dppc's simulation in NPT ensemble? In gromacs's homepage, it provides two force field modified for lipid's simulation, and one of them(ffgmx_lipids.tar.gz) could work with dppc.itp from Dr. Peter Tieleman's website and the other one could not. which one is the better?
