Hi Michael, You may have just noticed, but the bieri_gui branch has now been finally merged into the relax 1.3 main line ;) The process was quite painful - all of the auto_analyses changes should have gone into the 1.3 line, and only the 1.3 line. There were a number of other issue too due to the same code being worked on in the 1.3 line and in the bieri_gui branch. Anyway, the GUI is now in a very good shape for relax 1.3.9. I have updated http://www.nmr-relax.com/download.html to include the wxPython dependency. I have also updated the relax manual a little to include a screenshot and to no longer say that the GUI is not implemented :) Ideally the manual could be updated with GUI screenshots in all of the NOE, R1, R2, and model-free chapters to complement the current script-based description. If you would like to add pretty pictures to the manual, to add a page describing the GUI at http://www.nmr-relax.com, or see some other way to better show off the GUI to potential users, please feel free. But it isn't essential as the paper is on the way and what is currently written seems sufficient to me. I think after all of this we should go out for a beer to celebrate (when our paths cross again). Cheers! Edward
