There are two separate questions at hand here. The first is: which method for
calculating free energies is appropriate to the system at hand? The second is:
how do I do that in Gromacs? I can't help you with the first; no one on this
list can because there's too much that we don't know. Your job is to survey the
literature and consult with colleagues/supervisors for recommendations.
Studying ion binding to proteins is not a new idea. Once you have a direct
approach that you wish to use within Gromacs, that's where those of us on the
list can help.
