Hi,
I am using the Umbrella sampling technique in AMBER 8 to calculate the
potential of mean force between two molecules. I use the distance between
their center of masses as the reaction coordinate. Is there any way to use
the reaction coordinate as the distance in x-direction while maintaining
their y and z - coordinates unchanged? To be more clear, I would like to
know if I can use position restraint on molecule 1 and pull the molecule 2
away from molecule 1 in only x-direction? Thanks for your inputs in advance.
