I don't know of any parameters for ion interactions with methanol or
cholorform. Are you sure that you still have a charged protein (esp. with
ChCl3)? If this is more of a model (or theoretical) study, you might
consider not including ions, and let the uniform background charge from PME
handle the neutralization.
