Hello, Thomas
Even if it is not implemented at the moment I guess I can implement some code by myself. However, I still would like to know if I can use the trajectories from my TI simulations, to get the values I need to compute the Bennett acceptance ratio. I'm not sure what information the mdcrd file contains for the V0 and V1 states, and if I can use some code of mine to calculate the potential energy along the trajectories, in order to compute the Bennett acceptance ratio. I would like you to tell me if it is possible from a theoretical point of view, sort to say.
Hope I made myself clear,
Kind regards,
Samuel

Hi Samuel,
unfortunately, the Bennett acceptance ratio method is not implemented in
the Amber TI code at the moment. It is on the list of things to maybe be
put into it in the near future, though.
Kind Regards,
Thomas
