Comment:

I have simplified the Run.dat to leave out the METS selector and show that the same issue happens even with just a normal pT selector. Also, the nan seems to be Comix specific... at least a simple process like in the modified Run.dat's above does work with Amegic (which seems to have a different issue with containers, filed in a separate ticket). Running this with Comix, the Amplitude::EvaluateAll returns a nan even though the momenta look reasonable (large enough pT).

    46 I thought the METS jet finder is applied on the single process level, so I don't quite understand why this makes a difference here.
