Re: Lipids into NAMD

The Benoit Roux lab has libraries of pre-equilibrated DMPC and DPPC in
CHARMM format.

You can easily read them with VMD and then save them as pdb. Some lipids
are already present in the CHARMM topology file as a whole, others need
to be built by patching together tails and polar head.

You can find the topology and parameter files here:

If you have access to the CHARMM program, you can build basically any
type of lipids you want, by patching the existing tails and polar heads
together. If the patch you need doesn't exist in the topology file, you
can always create your own. You save then the psf file in xplor format
and use that for namd.

Hope this helps,
