[gmx-users] Fixing periodicity effects on trajectory file

2015-09-15 Thread Homa rooz
Hi there I'm working with gromacs for ligand-protein interaction simulation. I have run MD for docked complex and now there is a problem with trajectory visualization by VMD. The ligand has left binding site circulating around the protein. I tried to fix the problem by making index and extract the

Maybe the ligand actually is leaving the binding site and moving around, and that's what your simulation is telling you! Hard to say with the posted information. On Tue, Sep 15, 2015 at 11:24 AM, Homa rooz wrote: > Dear Justin > I have followed your advice but it didn't solve my problem. > Ligan
