[Rivet] Problem in Writing Analysis in the RIVET

[Andy Buckley]

Hi Andre,

You seem to have set your RIVET_ANALYSIS_PATH correctly: it contains the 
path (or paths) where your plugin .so file is to be found. There will be 
an automatic fallback to include the "system" Rivet analysis directory 
unless you take active action to stop it. The RIVET_ANALYSIS_PATH will 
also be used to find .info, .yoda, and .plot files unless you set 
special variables for those types of file searches (which ~no-one does).

So in your case it's working fine, except that you don't have a .yoda 
reference data file for your analysis. This isn't necessary, unless you 
make a call like bookHisto1D(1,1,1) or 
bookHisto1D("some_ref_histo_name"), in which case it looks for a ref 
data file to get the equivalent ref histo's binning from.

You can get a .yoda file from the HepData system, if your analysis is in 
there, or make one by hand: take a look at some of the existing ones in 
your Rivet installation's share/Rivet directory to see how the format works.
