Hi,
I have a problem with the error analysis of g_wham. The PMF profile and
sampling windows looks good, but when I try to generate error bars g_wham
hangs. This is what I do:
g_wham_mpi -if pullf-files.dat -it tpr-files.dat -o -hist -nBootstrap 50 -bins
50 -bs-method traj-gauss -bsres -ac yes -bsprof -vbs
This is the output after which it just hangs:
Estimating integrated autocorreltion times ... [100%] ... done
