[Rivet] Rivet 2.0.0

[Andy Buckley]

Thanks Sarah -- glad you got it working with the "experimental"
(actually quite stable, just hand-made!) build. That error from the
Genser area looks pretty weird to me -- I would guess it's a compiler
incompatibility thing.

I'll look into it, certainly when we release Rivet 2.1.0 and maybe
before, and make sure that we have some instructions for using the
Genser copy that actually work! Thanks again.

Andy

It doesn't matter for now as I can use the experimental version but I though I should let you know anyway.

I have re-read the slides you prepared for the tutorial and can see how you said to run the code there but I am still a bit confused as to how to run over a particular dataset. For example in this case I would like to run over a the 1fb-1/5fb-1 dataset or a particular set of MC files which I have downloaded. Is there some help you could give with this or somewhere you could point me which would have a little more information. (Sorry if this is a little basic but I am a beginner at this)
