Re: [gmx-users] no subject

Hello Faisal, Easiest way to do this is by navigating to the MD files tab and download the "Gromacs 4.5.x-5.x.x 54a7" below this warning - "*Warning!* This molecule contains non-standard atom types not included in the standard GROMOS 54A7 forcefield..." The folder contains the procedure to modify

[gmx-users] Reproducibility of a PMF plot

Dear all, Of course it is always good to prove that a MD simulation is reproducible by repeating several replicas of a simulation and then average over the quantity of interest, specially for a publishable result. I wonder if that also is necessary for a potential of mean force (PMF) calculation u
