[gmx-users] Convergence

[Billy Williams-Noonan]

Hey Justin, out of interest, when the PMF flattens at the end (the rate of
change is zero), how do we know that the PMF has truly converged?  Is there
some mathematical tool that can tell you the likelihood that the entire
conformational space has been sampled adequately?
