Dear Justin, Do I need to add lipid topology manually, if I use Charmm36 force filed that have protein and lipid parameters together? Thanks Anu On Fri, Jul 3, 2015 at 4:47 PM, Justin Lemkul jalem...@vt.edu wrote: On 7/3/15 7:56 AM, anu chandra wrote: Dear Gromacs users, I am working

Hi, You need a topology for each moleculetype, and parameters for the interactions they require. These are separate issues. Mark On Mon, 6 Jul 2015 13:05 anu chandra anu80...@gmail.com wrote: Dear Justin, Do I need to add lipid topology manually, if I use Charmm36 force filed that have

Dear Gromacs users, I am working with membrane proteins. I have generated the membrane-protein system ( contains lipids, protein, water and ions) with some specification. For eg., I have positioned few ions and water molecules at particular location using some in-house programs. Now, I would
