unfortunately not. It will be done eventually though: to follow the progress of that feature, check out: http://redmine.gromacs.org/issues/1346
If you have to do that, there is a patch that I posted on that same redmine page (posts 8 and 9) to allow this in gromacs 4.0.5. Chris. -- original message -- Thanks for your check. Yes, it should be pull_group2 for C. In this case, the two distances have a reference group B. What about the case in which no common reference group is shared with the two distances, e.g. distance1 is defined as A-B and distance2 as C-D? Can current gromacs codes perform 2D umbrella sampling for this problem? Many thanks.
