[Rivet] problems with RivetGun/Alpgen

[Holger Schulz]

Hi Peter,

to my knowledge, RivetGun does not exist anymore,
the wiki page hasn't been updated for more than three years.
Rivet is completely independent of any generator libraries now.
You will need agile to steer your (FORTRAN) generator and
rivet to analyse the HepMC output coming from agile.

I haven't run AlpGen with Rivet but the usual way
to go is to run agile with Alpgen to get the HepMC
output and feed it to Rivet using a fifo file buffer (create it
via mkfifo hepmc.fifo).



So your commandline should look somehting like this:

    agile-runmc AlpGenFpythiaVERSION -o hepmc.fifo -n 10000 & rivet
    hepmc.fifo -a ALEPH_1991_S2435284 -H output.aida

Does that help?
