Hi Gromacs users,
I'm doing protein-Bilayer MD simulations. Enzyme contains structural zinc
and calcium ions during Energy minimization, NVT and NPT stage, ions are
changing there position even though I applied position restraints for the
atoms and ions.
Anyone could help me out.
If the atoms are moving drastically, then the position restraints aren't taking
effect, either because they haven't been invoked or they are insufficient.
Without your full .mdp file and relevant topology snippets, there's no real way
to know. You can check the .log files, too - if there is not an energy
component corresponding to position restraints, they haven't been activated.
