Thank you Parham and Justin,
Excuse me I have another question, in simulation of a water-peptide system, is
it necessary to use QM/MM simulation during the entire process? Because I
didn't see it in the tutorials. By the way I generated the pdb file by using
charmm-gui then import it in amber to get the topology and coordinate files,
finally I converted the topology and coordinate files to gromacs format and did
the rest of simulation by gromacs. but I didn't run QM/MM simulation. Does it
make trouble in the results?
Best, Mohammad.

The trivial task of adding ions to neutralize the net charge on the system
certainly does not require anything like QM/MM.
