Dear developers, While trying to run mr.rosetta from the GUI, I've encountered an error (see screenshot). I have un-checked the box Include solvation energy. The file rosetta_weights.wts has been created in WORK_1, fa_sol=0.0. Inspection of mr_rosetta_params.eff in GROUP_OF_PLACE_MODEL_1 revealed include_solvation_energy = False, followed by weights_file = "/Users/abatyuk/Desktop/o1map/MR_ROSETTA_74/WORK_1/rosetta_weights.wts", but it seems that the GUI wants either or. Is that the expected behavior? I'm running 1.8-1056, Rosetta 3.4 on OS X 10.6.8 Best wishes, Alex -- Alex Batyuk The Plueckthun Lab www.bioc.uzh.ch/plueckthun
