Dear Phenix Users, I am interested in using Rosetta to do MR, but unfortunately I have encountered some problems in installing it: I was able to get to the step where "scons: done building targets." showed up, and set up the environment by typing setenv /Users/yanghai/Desktop/rosetta-3.5 into the shell. I also filled out the "path to rosetta" in "Preferences" under "PHENIX GUI", which I believe it is correct. However, when I was ready to run MR-rosetta, it kept saying "cannot locate Rosetta programs. You may set the path in PHENIX GUI under preferences->Automation, or define the environment variable PHENIX_ROSETTA_PATH (recommended)". Any help would be apprecited! Thank you in advance, Mengbin Chen -- Mengbin Chen Department of Chemistry University of Pennsylvania
