Dear Justin I did pmf calculation for my protein-protein complex using your tutorial.Off course changing the pull_direction suitable for my protein but more or less following the same strategy. I am using gromacs_4.5.4 and g_wham utility. The profile.xvg file which I get is attached and it shows two dips in PE curve. Please see it and tell me why I am getting these dips. Shahid Nayeem
