Running SHERPA+Rivet as installed at CERN fails?

[Generic User (don't modify these fields)]

I'm working at CERN with lxplus using the installed Sherpa system. I have a link in my home directors, ~/Sherpa -> /afs/cern.ch/sw/lcg/external/MCGenerators_hepmc2.06.05/sherpa/1.3.1/x86_64-slc5-gcc43-opt/bin/Sherpa

I copied the directory /afs/cern.ch/sw/lcg/external/MCGenerators_hepmc2.06.05/sherpa/1.3.1/x86_64-slc5-gcc43-opt/share/SHERPA-MC/Examples/LEP91 in my home directors, and augmented Run.dat (attached) by a Rivet analysis section. The Rivet analysis OPAL_2004_S6132243 is an event shape analysis I'm interested in.

Running

pahl2@lxplus442:~/LEP91$ ~/Sherpa ANALYSIS=Rivet

gives the attached file ~/LEP91/Analysis.aida .

I cannot do anything with this file: 1) It is an .xml file, but not zipped, as .aida files usually are. Ok, I can do this myself. 2) The .xml file looks strange, the histograms seem to lack sensible titles (compared somewhat to other .aida files). 3) I tried to read in this file, using two different systems (JAS3 und jhepwork). This doesn't work, giving the message "Error opening file".

I also tried sherpa version 1.3.1.2 and/or Rivet analysis OPAL_2001_S4553896 and/or Sherpa example Tevatron_QCD with Rivet analyses D0_2008_S7662670 CDF_2007_S7057202 D0_2004_S5992206 CDF_2008_S7828950, but never got an .aida file which was usable.

Your .aida files is perfectly fine, and I can look at the plots without any problems, using "rivet-mkhtml Analysis.aida" and a web browser or pdf-viewer (see Rivet manual for details).

1) .aida files usually aren't zipped.

2) Histogram titles and labels don't need to be stored in the aida files. In fact, Rivet stores them separately in .plot files which are read e.g. by rivet-mkhtml.

3) For any problems with JAS or jhepwork, contact the corresponding authors of those tools.
