ERROR: invalid event format

Asked by Blake Forland on 2017-02-27

I've produced a HEPMC from MagGraph, but when trying to use it with DelphesHepMC, get the error:

** ERROR: invalid event format--------------------------------------] (0.00%)
** [################################################################] (100.00%)
** Exiting...

My command that leads to this error is:

DelphesHepMC ~/Research/MG5_aMC_v2_5_2/Delphes/cards/delphes_card_ATLAS.tcl output.root tag_1_pythia8_events.hepmc

I'm not sure why I'm getting this error.

Hi,

We are not able to produce any HepMC format.
Some external program (like pythia8 or herwig7/++) can generate such format but we are not able to.
So this is a problem between PYthia8 and Delphes.

I have created a ticket on Delphes tracking system:
https://cp3.irmp.ucl.ac.be/projects/delphes/ticket/1078

Cheers,

Olivier
