hello, i want to calculate the contact map between two different proteins. Using mdmat it is possible to calculate the contact map within a protein. But can anyone please suggest me how i can calculate the inter-residue contact map between two proteins using gromacs. thanking you shahee --

Hi...you can use charmm gui...for generating the topology for a lipid by layers.. it's much easier way to do... On Wed 14 Aug, 2019, 12:28 PM Atila Petrosian, wrote: > Dear gromacs users, > > I want to do MD simulation of the lipid bilayer-ligand system. > I used MD topology file from Automated

[gmx-users] topology files for lipid bilayer

2019-08-14 Thread Atila Petrosian
Dear gromacs users, I want to do MD simulation of the lipid bilayer-ligand system. I used MD topology file from Automated Topology Builder (ATB). ATB got GROMACS G54A7FF United-Atom (ITP file) for ligand molecule. How to get appropriate topology files for lipid bilayer? Please guide me about
