I am trying to carry out a 2D PMF calculations of two ions in a peptidic channel using GROMACS (and Umbrella Sampling).
I have several technical questions:
-Should I consider pull_ngroups = 3 (two of them ions and the other one the channel)?
should I carry out a 1D PMF for one of the ions (leaving the other ion
free), and then doing the same for the other ion and combine the
results? In that case is there any tool for combining the results
obtained for both ions? I have seen 2d-wham, but it is not implemented in GROMACS, is it?
Thanks a lot in advance.
