[gmx-users] Umbrella - Force constant

2012-07-03 Thread Steven Neumann
Dear Gmx Users, Do you know or can you suggest some results based on the comparison of the force constant in Umbrell Sampling? Any literature? As far as I understand when you use the same staring coordinates (from the same pulling simulation) for windows but you just change the force constant

It also depends in some cases strongly on the system. I have a two-state system in which both states are rather narrow (doing a normal pulling simulation, the end-to-end-distance seems nearly constant). In these two regions one could use small force constants. but both state are seperated by a
