[Rivet] YODA::UserError with ATLAS_2014_I1307243

[Andy Buckley]

Hi Jannik,

To fix the problem you would at least need to update to a more recent 
version of YODA. This is separate from Rivet, but I can't *guarantee* 
that Rivet 2.2.0 will work with e.g. YODA 1.3.1 since that YODA was 
released long after that Rivet and we don't test such combinations.

However, I have to say that I *wrote* the ATLAS tuning framework, and it 
includes a script (mktuninglocal) to build a self-contained environment 
of tuning job packages, including Rivet and YODA. These are downloaded 
in the script, and the version numbers can be modified... so I strongly 
suggest updating to the latest YODA 1.3.1, Rivet 2.3.0 combination where 
you'll benefit from this bugfix *and* many others.

If you have trouble with that, let's sort it out on the ATLAS tuning 
list because it's not a Rivet issue.
