Re: [gmx-users] PMF and lack if NPT equilibration

Thanks. I used the "direction-periodic", along with "semiisotropic" with zero compressibility in Z direction to have also NPT equilibration in each windows. Below is the final pressure after NPT equilibration with 1 bar reference, I hope it would be ok?! Energy Average

Thanks for your response. My question is not in the sampling step as I have already pulled away two parts and even picked out the configuration of each windows. But my question is about simulation in each individual windows toward WHAM. You means in the step six of the tutorial no necessarily

Dear gromacs user, In a PMF simulation of a short peptide on solid surface, I am using the "direction-periodic" as "pull-coord1-geometry" in the Z direction, then as you know the equilibration of the system in NPT ensemble is not doable for the individual windows. So, for each windows of
