Hello,

I am using steered MD and umbrella sampling to generate a PMF profile for 
pulling a small ligand 3 nm.  As I pull the ligand from 3A toward 0 A, the PMF 
starts  a dramatic uphill climb. This does not agree with the force profile 
which seems to level out. Any ideas about what might be going wrong here? I am 
thinking this probably isn't correct, but I don't know where I've messed up. 
Thanks! I can attach the graphs if necessary.

- Laura
