Hi, Probably the "CHARMM27_protein+Charmm36_lipids" version. AFAIK, the second version was not already converted in GROMACS format.
Stephane --------------------------------------------------- hello: I found a charmm36.tar.gz in Gromacs website GROMACS 4.5.4 version of the CHARMM36 force field files. These updated CHARMM lipids allow the all-atom simulations of membrane and membrane-protein systems without the use of surface tension. Check out the forcefield.doc for more information regarding these files 71.65 kB 15:42, 25 Sep 2012 TomPiggot I am just wondering, is the the one with CHARMM27_protein+Charmm36_lipids or it is CHARMM36_protein+CHARMM36_lipids? thank you very much best Albert -- gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.
