However, at least in Rivet 2.4.0, I noticed a bug in the way the name of an AnalysisHandler object is used to make the YODA histogram path (see Analysis::histoDir) and then in the way the same runName is used by the Rivet helper scripts to create the web page for the analysis results. In the first case runName is just another "branch" of the YODA path while the script rivet-cmphistos attaches the runName to the analysis name using underscore. This creates a problem when make-plots interprets the *.dat files as the plot meta data is no longer identified correctly in the corresponding *.plot/info file. The result is a web page that has neither analysis description nor plots with valid labels and titles (although the environment variables are set such as the meta data of the analyses should be found). I'm using the Rivet installation on lxplus at this path: /afs/cern.ch/sw/lcg/releases/MCGenerators/rivet/2.4.0-dd72f/x86_64-slc6-gcc48-opt. Could you please investigate and advise the maintainers to correct these issues if they are installation related. It is quite annoying to have a feature such as the runName if it is useless and it actually breaks things. I noticed however that if runName is set to an empty string everything works fine. So maybe it would be a good idea to explain, for developers, what is the purpose of this runName property. In the mean time I'll just instruct the LHCb users not to care about this feature when testing their analysis modules. Thank you in advance.
