[gmx-users] calculating free energy

How about temperature replica exchange with de novo folding, then convert the probabilities of the folded and unfolded states into a free energy difference? You'll obviously need to be really careful about cutting off a sufficient amount of initial simulation time as equilibration, but you might be able to get a good idea of how much to cut if you repeated it once from unfolded and once from folded.

Subject: [gmx-users] calculating free energy
I know there are some methods for calculating free energy of* binding*
between a ligand and a receptor.
1.Are there any methods for calculating free energy of *unfolding *proteins?
4_helix bundle protein makes my system,
2.Is scientifically reasonable for my system to calculate free energy in
the same way as described in tutorial number 6, methane in water ( coupling
parameter : vdw interaction)?
any help is appreciated.
