Dear Amber Users,
I am running a QMMM MD simulation. The system is 28 atoms large (not
including waters). When I view the trajectory, the molecule begins to
oscillate wildly and becomes very distrorted by the end of a 1000fs
run. I reduced my time step to 0.5 fs but still have the same
problem. Do I need to put some restraints on my solute? If so, what
is the syntax for applying a restraint on a set of atoms with the
ntr=1 option in a QMMM.in file.
Thanks,
Seth
