Dear Boaz, We're glad you like the ConSurf/Chimera setup! The error log you sent says this: trying to import std_webdata Error reading /home/boaz/data/esrf_nov04/esrf_gcl3/consurf/ pdb2pan_isd.chimerax: Couldn't find url 'http://consurf.tau.ac.il/results/1234779578/ isd_pdb2pan_view_ConSurf.pdb': Received HTTP error 404 ('Not Found') trying to import std_webdata Error reading /home/boaz/data/esrf_nov04/esrf_gcl3/consurf/ consurf_1234779578.chimerax: Couldn't find url 'http://consurf.tau.ac.il/results/1234779578/ pdb2pan_view_ConSurf.pdb': Received HTTP error 404 ('Not Found') which I can only interpret as some problem finding the file at the ConSurf site - maybe there was some error in creating the pdb file, or for some other reason the URL given in the chimerax file (Chimera Web data) from ConSurf is incorrect. You could also try entering those URLs directly into a Web browser on your machine, to make sure it is not related to Chimera. Did you have that chimerax file around for a long time? The ConSurf people must remove the results files periodically from their site. If you want to keep the results yourself long term, I think you have to also download all the files from the URLs given in the chimerax file, and then edit the chimerax file to point to them locally. It sounds like you have successfully viewed ConSurf results in Chimera before, so that is my best guess of what is happening. Regards, Elaine ----- Elaine C.
