Hi, As the relaxation dispersion analysis in relax is almost complete within the relax_disp branch, I will look at merging this branch back into the relax trunk probably early next week. Please say if this will affect you. I will also then release relax version 3.1.0 with support for dispersion data. The change in minor number from 3.0 to 3.1 will be made due to the large number of changes that this relax_disp branch holds. Future developments of the dispersion analysis can then occur in new dedicated branches. Regards, Edward
