2017-02-14 Thread ashutosh srivastava
Hi everyone I have written a python script that takes ligand group name as input and then does some analysis. However, the default groups that come out have repeated instances of ligand name and ions. Upon giving the ligand name as argument it throws following error. Error: Multiple groups 'MOL' s

[gmx-users] Problem in PCA of protein ligand system

2016-09-25 Thread ashutosh srivastava
Dear all I have performed a 200 ns simulation on a protein ligand (MOL) system in gromacs 5.1.2. Is it possible to get low frequency motions of only the ligand? When I am looking at the filtered trajectory (along PC1) after performing PCA on the protein+MOL the small molecule looks distorted. The

Hi Aswathy You can make a group with Protein and ligand in an index file using make_ndx and pass it with -n in gmx rms. Ashutosh On Fri, Apr 22, 2016 at 6:46 PM, Aswathy soman wrote: > Hi, > I have done a 100 ns simulation of protein-ligand complex. I was wondering > is it possible to calculat
