Dear Users and masters! I know that gromacs can prepare the topology with covalent bonding of cys-cys bridges in the individual chain on fly. However, when two different chains are connected with such bonds and the intital geometry is satisfactory (distance, angle) It doesn't work. It was done

Dear gromacs users, I have a system with a topology generated from Amber and then converted through ParmEd into gromacs-formatted stuff. I would like to add distance restraints for several pairs of atoms (ca 20). Is it possible to add them with grompp or should I edit the .top file some way?

Hi, The gmx pairdist tool has a lot of capabilities that look like you can already do exactly what you want, either with multiple selections or well chosen grouping within selections. Do check the docs. Mark On Sat., 9 Mar. 2019, 15:00 Pandya, Akash, wrote: > Hi all, > > > My protein is 168

[gmx-users] Pairwise distances from COM of residues

2019-03-09 Thread Pandya, Akash
Hi all, My protein is 168 amino acid residues long. I want to calculate the pairwise distance between the COM of each individual residue and my ligand molecules during my trajectory. As I have 168 amino acids, this will take ages if I run the gmx pairdist code each time. I was wondering

Hello Dear All I did a simulation of protein-protein interaction. I want to obtain a distance residue between the two proteins. In the Gromacs tutorial has been said to calculate of distance for protein-ligand whereas I want to calculate of distance for protein-protein. The command of
