Hi, I am planning in a few weeks time on merging the frame_order_cleanup branch back into the relax trunk. Despite the name, this branch is a huge change containing many, many commits and it completes the frame order theory implementation in relax - which in trunk is very rudimentary, incomplete and unusable - and brings it up to publication quality. The merger of the new theory will correspond to a publication. As this change is so big and brings in a completely new analysis category into relax, I am thinking of incrementing the major version number and releasing this as relax 4.0. Regards, Edward
