Antonio showed me a segfault on the snap analysis computer from FindSNSNexus called from the CalibrateRectangularDetectors python algorithm. Temporary fix was to copy event nexus file into working directory.

Pete upgraded snap to the latest release which should fix this problem. I will leave this ticket open in case this happens again.

This problem is caused by Mantid on Rhel5 using python2.4. Temporary fix is:

cp /SNS/software/lib/python2.5/site-packages/findnexus_lib.py /usr/lib/python2.4/site-packages

FindSNSNexus does not work for files that contain "_histo"

FindSNSNeXus-[Error] Error in execution of algorithm FindSNSNeXus:

FindSNSNeXus-[Error] Python error: File "/SNSlocal/SNAP/IPTS-4098/0/6416/NeXus/SNAP_6416.nxs" does not exist

at line 80 in '/opt/Mantid/plugins/PythonAlgs/FindSNSNeXus.py'

Couldn't test this on my machine; version on SNAP is too old.

Is there any particular dataset to use for testing ?

Tried with some random values for run SNAP 7000. The algorithm doesn't work completely as I am probably using rubbish values, but it does get past the FindSNSNexus without a problem.

Only problem was that I needed to install findnexus into the system python first!
