Thanks Chris. -----Original Message----- From: gmx-users-boun...@gromacs.org [mailto:gmx-users-boun...@gromacs.org] On Behalf Of Christopher Neale Sent: Thursday, September 26, 2013 7:47 PM To: gmx-users@gromacs.org Subject: [gmx-users] Membrane simulation with OPLS ff.
Dear Karthi: As far as I am aware, there is no OPLSAA lipid force field. I have used Berger lipids with OPLSAA protein ( http://www.pomeslab.com/files/lipidCombinationRules.pdf ) but that is mixing a UA lipid with an AA protein so be aware of possible problems arising out of that. Charmm has proteins and lipids, but charmm lipids require charmm tip3p water (or at least tip4p or spc, certainly not regular tip3p) and are thus slower to simulate in gromacs. I'm more recently using the Slipids (stockholm lipids) and Amber99SB-ILDN protein forcefield. Chris. -- original message -- Is OPLSAA forcefield data already available for POPC membranes. I am interested in simulation of proteins in POPC membrane. Thank you.
