Hi Stefan, The executable required to compute small-angle x-ray scattering (SAXS) profiles comes from Andrej Sali's lab at UCSF and is currently not distributed with Chimera due to licensing issues. It is also not available directly from them for the same reason. It will probably not be available for some months. So I've taken the proto-type SAXS plotting tool out of the Chimera distribution. I should not have included it in the daily builds. There are other SAXS profile calculation programs. See for example CRYSOL http://www.embl-hamburg.de/ExternalInfo/Research/Sax/software.html Tom -------- Original Message -------- Subject: [Chimera-users] problem with SAXS profile From: Stefan Jehle To: chimera-users Date: 10/25/09 12:15 PM

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
