[gmx-users] ligand-protein simulation
Dear all gromacs users, I have run a protein-ligand simulations. However, the position of the ligand is not reasonable after 10ns simulation. There is no problem with the force field paramers of the ligand. I am trying to constrict the ligand move for 500ps simulation. But i do not know whether it will work. Any good idea is appreciated :) Best wishes Fugui-- gmx-users mailing listgmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/Search before posting! * Please don't post (un)subscribe requests to the list.

Any good idea is appreciated :) Usually when something misbehaves, the topology is the first likely source of error. How have you concluded that it is suitable? Since we don't know what you're doing (description of your protocol, or even better, .mdp files), it could simply be that you're doing something that causes the physical model to be wrong. Provide that information and you're more likely to get a quick and productive response. -Justin -- == Justin A.

Re:Re: [gmx-users] ligand-protein simulation
Hi Justin, Thank you very much for your response. I used GAFF force field parameters for the ligand. I have done another short MD simulation, and this time everything seems fine, so i have no idea where the problem is from.
