[gmx-users] Jarzinsky's inequality from SMD simulation

I do not think Justin Lemkul's tutorial is suggesting extracting PMF using SMD simulation. What is does that it uses SMD to generate the initial configurations for different windows and then perform umbrella sampling separately on each windows to subsequently extract the PMF using WHAM based on the data set on umbrella sampling.

There is a way to extract the PMF from sMD simulations using the weighted histogram analysis method (WHAM) in gromacs- Justin Lemkul's tutorial does a nice job of explaining it:
