Hello
I am trying run g_wham for umbrella sampling.

Before going for sampling I want to plot PMF.

I have one .tpr file and one one pullf.xvg. How can I use them to run P<F>


You can't. Umbrella sampling implies that you've done simulations in multiple sampling windows along a reaction coordinate. That's why the input files for g_wham are .dat files that list file names of all the .tpr and pullf/x.xvg files obtained from these simulations. There's a tutorial linked from the Gromacs site.
