Hi Hannes,

The Rivet AIDA files don't store enough information for fully-fledged 
statistical combination, so we don't provide any official scripts to do 
it. However, you might find this useful:

http://svn.hepforge.org/rivet/contrib/aidamerge

This assumes that the AIDA files supplied on the command line contain 
equivalent histograms with equal numbers of events, and the outputs are 
averaged over the number of files, which is probably most suitable for 
profile histograms, but it should still be useful, and 
extension/conversion is very easy.

An update of the Rivet histogramming to automatically do combination 
like this is quite well advanced, but will not be available until 
version 2.0.
