Re: eABF - Fullsamples and windows merging

1. I often set fullsamples to 1000 for 1D reaction coordinate and 500
for 2D. For more information you can read the review:

2. You can get the colvars source code from and compile the abf_integrate in the
colvartools directory, and then run abf_integrate with your grad and
count file to get the final PMF.
