Hi Andy, 

thanks. I will have a look at the docs!

Cheers,

I didn't yet make examples for everything you asked about, but hist.scaleW(factor) will scale a histogram's weights, summing is just h1+h2, and histo division is h1/h2 -- the last of which returns a Scatter2D rather than a Histo1D.

At that point writing your own script makes sense, IMHO.

Whenever one needs to run multiple jobs to get enough statistics or to combine different process it is a pain to do even simple operations (yodamerge doesn’t cover all possible situation and I don’t know where I can find some documentation to write my own python script).

Would that work for Christian, Holger, and whoever else is interested in helping? Would that work for the CMS GEN group?

I am too constrained to make the trip myself, but a couple of others from the Rivet dev collective (Chris and Christian) were keen to have a general-access (i.e. also theorists and other experiments) tutorial at CERN in the near future. Would that suit?

For family reasons I personally have trouble travelling at the moment, but this is definitely the sort of thing that we want to support and I hope that one (or more?) of the other team members could come and give a tutorial -- I guess you want to run it at CERN? And any idea of timescale?
