To generate each window I use "trjconv -f original_separation_trajectory.xtc
-s topol.tpr -dump time_where_specific_distance_is_found -o
Once I have the coordinate files regarding this specific distance between my
pull groups, I simulate each of them (using the same topol.top file,
index.ndx...etc) but with the new md_pull.mdp file I've shown here earlier.
Is this wrong for wham analysis?
Thank you
