I have read the Free Energy Tutorial from the Dill group wiki and found it very informative on how I should set up the top file and the experiment as a whole. But I can't seem to get the jobs to run correctly. I am assuming that the top file is incorrectly setup as the jobs run with lambda = 0. | ----------------------------------------------------------- It sounds to me more like your .mdp might be wrong. Check out the FE section of manual 7.3 Mark
