[gmx-users] Free energy calculations using tabulated potential

[Gianluca DEL FRATE]

Dear GMX users,
I am simulating metal ions in water by using user tabulated potentials to
reproduce a customized force field pretty different from the standard
12-6-1.
Is it possible to compute the free energy of hydration with BAR method by
using potentials in this form?

Thanks in advance
Gianluca
