thank you for the rational explanation. but is the free energy change in the charge on/off step(~10kJ/mol) small enough to ignore the flucturations? The free energy change in the LJ mutation step is about 8kJ/mol. On Fri, Jan 16, 2009 at 11:56 PM, Jochen Hub wrote: > friendli wrote: > > Dear al

Dear all, When I performing mutation free energy calculation from Leu to Ala, I first turn off the charge on the side chain of Leu. As I read from the GMX archive, the dG/dl curve should be rather smooth for turning off the partial charge. In this step(charge off/on), however, I can not obtai
