The default behaviour should probably be to have histograms for each item in the weightcontainer. Sherpas, Herwigs and Pythias would like to tell Rivet which weightnames of the container in hepmc they want histograms for as they tend to abuse the weight containers for debug info etc. This should be done using regexes just like the -m -M switches, I would propose -W and -w for that purpose. Similarly for plotting. The whole nominals central weight discussion could be circumvented if we <ul> <li>check on initialisation if there is more than one weight in the first place </li> <li>treat all weights the same, i.e. always write out PATH[weightname]</li> <li>tell the plotter what the central weight is --- if there is more than 1</li> <li>If there is just one histogram per observable only plot that of course </li> </ul> In that way one would be most flexible whilst retaining the rivet2 cmdline of rivet-mkhtml bla.yoda For the multiweightcase one could do rivet-mkhtml -c "Weight" -e MUR -E PDF_2610 output.yoda i.e. specify the central weightname and use regex magic to determine what goes into the envelope and what does not. That would also make rivet immune to changs in the standard naming for variations. From the feedback I got here, people are not too happy having to obey to the MUF_MUR_PDF naming scheme. Any non-trivial thoughts on that? ;) Holger </body> </html>
