Using heprep files with wired in jas3 with variant geometries [message #1908] Wed, 27 January 2010 19:26

When viewing events from a variant detector geometry in wired, jas3 will ask for the heprep file for the given geometry either as a direct path to the heprep file or as an alias to the heprep file.

If you give a complete filespec to the correct heprep file, jas3 will give an error concerning line 59 of org.lcsim.util.heprep.MCParticleConverter. The line is:

trackingRMax = detector.getConstants().get("tracking_region_radius").getValue();

However, this information (the tracking region radius) is not in the heprep file in any case, it's in the compact.xml file. So it seems this particular method of loading the heprep file alone can never work--is this a bug/feature?

Taking the other option--putting an alias to the detector conditions data in your ~/.lcsim/ file--will work, but only if the directory does contain the compact.xml file.

Just FYI.
