Please the histogram generated. It does not show any window overlap.
You have some regions where the overlap is good, some where it is weak, and some
where it is nonexistent. You either need more sampling or more windows to
capture the entire reaction coordinate. This is discussed in the tutorial.

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.
You have insufficient sampling in at least these two regions. Your
histograms should confirm this.
