Hi all, I am doing the umbrella sampling of a ligand pathway (Gromacs4.0.4).Now i want to plot the PMF using WHAM analysis by Alan Grossfield. I installed the WHAM program, read the manual too. But i am confused with the "loc_win_min" and "spring" terms in the metadata file.
Can anyone please explain me these two terms? I have the pullx files from 21 umbrella samplings.(I guess this will go as the first term in the meta data file.). Pull_k1 used for Us was 1000. Please let me know if you need any other details. Thanks in advance, -Aswathy
