[gmx-users] Conformation free energy

If you're just interested in the free energy of rotating a bond, I
would suggest umbrella sampling, as it's far more efficient for doing
that than doing the bond rotation alchemically, as you're suggesting.

I would like to quantify the probability of each conformation, so I thought of doing a FEP calculation. As I haven't seen much about this in the mailing lists, save for a D- L- amino acid calculation, I am wondering if there is a more obvious way to do this that I've overlooked? And if there isn't, what is the path to go from conformation 'A' to conformation 'B' in the top file?
