[gmx-users] Force constant for position restraints

[shahab shariati]

Hi gromacs users

there is a option in pdb2gmx command : -posrefc (Force constant for position
restraints).
and also there is following lines in top file:
#ifdef POSRES
#include "posre.itp"
#endif
which of them is better way for position restraint simulation and
determining of force constant?

Any help will highly appreciated!
