Hi,
 
I am using AMBER10. Assume there are two proteins A and B, orignially the distance between the center of mass of A and the center of mass of B is 1 Å and A is on the left side of B:
A B
what I want to do is to fix the distance to 5 Å, so I applied umbrella sampling method. Finally the system became:
A B
However, the result I want is:
B A
I do not know how to do this. Could anyone help me? Thanks a lot.
 
Sincerely,
Qian
