```Dear GMXusers,

I would like to reproduce the results obtained in the paper of Marrink et al
"Molecular dynamics simulations of the kinetics of spontaneous micelle
formation". J. Phys. Chem. B, 104:12165-12173, 2000". In this (old but
interesting) work, the authors used the GROMOS96 force field to model the
DPC lipid. I have found the topology file for the lipid in the P. Tieleman's
website but not the GROMOS96 lipid parameters. I have contacted one of the
authors (SJ Marrink), but unfortunately, he has not kept the files.

Does anyone know where I can find this file in the GROMACS format?

I have also found a "ffgmx_lipids.tar.gz" file in the "user contribution"
section of the GROMACS's website. Is this file is the GROMOS96 parameter for
lipids used in this paper above?
