It's really fascinating, how complicated and difficult very trivial things are in Rivet.

Here is some example syntax I use to check vertices: <blockquote>const GenEvent & hepmc = event.genEvent(); for (HepMC::GenEvent::vertex_const_iterator vtx = hepmc.vertices_begin() ; vtx != hepmc.vertices_end() ; ++vtx) { (*vtx)->print(); } </blockquote> and similar for particles coming from a decay vertex: <blockquote>const HepMC::GenParticle& genp = p.genParticle(); HepMC::GenVertex* decV = genp.end_vertex(); </blockquote> <blockquote>for (HepMC::GenVertex::particles_out_const_iterator pp = decV->particles_out_const_begin() ; pp != decV->particles_out_const_end() ; ++pp) { (*pp)->print(); </blockquote> } Hope that helps, Holger <blockquote cite="mid:B395C2ED-B4F9-4BC0-8562-11E1A77BEC42@cern.ch" type="cite"> <pre wrap=""> How do you people check, if selections etc are correct, if there is no way to printout what comes from the MC ? It would be really very good if this could be provided.... I tried to do it, but failed due to my ignorance in the Rivet structure... so if anyone can help there, I would be really, really very happy.... I try to promote Rivet for our summer-students.... so.........

The best I can think of offhand is, if you have a Particle p, to use p.genParticle().print(). Any other HepMC library function can also be used on the p.genEvent() reference.
