Hi, I have to finish very urgently a model of a big oligomer and the SAXS curve utility would be extremely helpfull for me if working properly. Here my problem: I get the following error message after pressing the "Profile" button: Wrote /var/folders/dP/dPWm0vEeFkG9xqa+tbipE++++TM/-Tmp-/tmprnvHi_.pdb Executing command: /Users/stefan/Downloads/Chimera.app/Contents/Resources/share/SAXS/ChimeraExtension.py /var/folders/dP/dPWm0vEeFkG9xqa+tbipE++++TM/-Tmp-/tmprnvHi_.pdb /Users/stefan/Documents/modelling/saxsprofile/abc30mer.dat Error 512 executing command "/Users/stefan/Downloads/Chimera.app/Contents/Resources/share/SAXS/ChimeraExtension.py /var/folders/dP/dPWm0vEeFkG9xqa+tbipE++++TM/-Tmp-/tmprnvHi_.pdb /Users/stefan/Documents/modelling/saxsprofile/abc30mer.dat" First I thought this may be because I have encrypted my cache (using MacOSX Leopard) but the same problem occurs using Win Vista or Windows XP or Windows Vista. I would appreciate your help, if you could provide me a saxs.py file working. Thanks a lot Best Regards Stefan __________________________________ Dr. Stefan Jehle Structural Biology Unit Leibniz Institute for Molecular Pharmacology, FMP Robert-Rössle-Str. 10 13125 Berlin Germany jehle@fmp-berlin.de Phone +49 30 94793232 Fax +49 30 94793169
