Hello. I am trying to access the videos from EMBO course available in Gromacs' wiki but I can't have access to any of them. Are they available only for a strict community or something like that? I also would like some advice on how to perform a calculation of free-energy of dimerization between two protein helices in a membrane model. I have read some works saying that they've done it using PMF. The problem is that I do not have much expertise on the matter and need some advice on what to read and what would be the best way to get information (both theoretical and practical) on the matter. Thank you in advance FabrÃcio Bracht _______________________________________________ gmx-users mailing list gmx-users@gromacs.org http://lists.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
