Dear users, I would like to perform an umbrella sampling by pulling two metal ions (two pull groups) away from protein (reference group) in opposite directions. I could restrain the positions of protein atoms (reference group) and then perform the pulling simulation. But how do I ensure that one ion will move in +Z direction, while the other in -Z direction?
Any help/suggestion is most welcome.
