Hi, I tried energy minimization and I am getting the error while I am
running the minimization step. But then I still tried to carry on with
normal md-simulation, and it was fine, but I am sure it won't give me
the result that it should. Is there a reason for that? I have tried very
low energy steps as well, but I am still getting the error.
If minimization still reports the same problems, then what I said before is
still true - you have bad contacts somewhere. Have you looked at the trajectory
to see where these problematic atoms are and what might be causing the clashes?
Sometimes running sufficiently gentle equilibration can relax away some of these
bad contacts, but that is rarely the case and often problems will manifest later
on in the course of MD. I would seriously consider re-evaluating however you
built your system (which you haven't told us) and try to get the energy
minimization to actually work before just plowing ahead with fingers crossed.
