hello @zalegria ,
Good to see that you have some jets!
You have the possibility to run your own jet clustering like shown here:
it does not include fancy sub-structure yet, but we could consider it.
The dictionary thing is really trivial, let me explain.
When you run analysis.py you will probably run over X events and select a subset, let’s say you end up with Y events. When producing histograms (what the finalSel.py does) you want those histograms to be normalised properly. Indeed all your processes have most likely a different cross section. The normalisation factor you have yo apply is somehting like (if you want it normalised to 1pb-1) XS(in pb)/number of processed events thus you need the cross section and the number of events you processed, and this is taken from the dictionary.
Cheers,
Clement
