Hi Hannes,

the AIDA file is badly formatted, i.e. it misses the "REF" prefix and the
analysis name in the histogram keys. This is what the keys look like at 
the moment:

    /d01-x01-y01

they need to look like this

    /REF/YOURANALYSISNAME/d01-x01-y01

I suggest you do

    aida2flat WZelectron.aida > temp.dat

then edit/sed  temp.dat accordingly and then call

    flat2aida temp.dat

This will give you the file temp.aida
In order to have this recognised by Rivet you need to rename the file to

    YOURANALYSISNAME.aida

and put it somewhere where Rivet can find it.
