[gmx-users] deltaG from PMF

[Steven Neumann]

Dear Gmx Users,

I got confused about reading free energy difference from PMF curve.
It is the difference between maximum value on PMF curve (plateau -
final state) and the starting point corresponding to minima.

So e.g. my curve starts at 0 [kcal/mol] going staright to minima of -2
kcal/mol and then increase obtaining plateau of 14 kcal/mol. DeltaG =
-16 kcal/mol or -12 kcal/mol ?

Please clarify me this,

Steven
