Dear all,

     I want to calculate the ion solvation free energy (e.g. an ion
Na+ solvated in a water box) using Bennett Acceptance Ratio (BAR)
method, following the tutorial by Justin A. Lemkul. However, if I turn
off the Coulombic interaction, the total charge of my system would not
neutral at all. Does this affact my calculation?
