[gmx-users] reliability of PMF

[abhisek Mondal]

Hi,

I've been trying to study a protein-ligand PMF using umbrella sampling
strategy.

So far, I have obtained the PMF following the tutorial and after performing
bootstrapping the error is estimated to be at most 0.4 kcal/mol.

Now, given the error value can I comment about changes like 2-3 kcal/mol in
PMF ? I mean, with this error rate, how precise I can consider my PMF curve
?

Any comments and/or references would be highly appreciated.

Thank you
