Description
Dear experts,
I'm trying to interface pythia8 output to Delphes-3.4.2, the pythia8 is interfaced with hepmc323, it seems the format of hepmc323 doesn't fit to Delphes-3.4.2, do i understand correctly, if yes, which version of hepmc3 is compatible with Delphes-3.4.2?
Cheers,
Meng

I think that the easiest solution at the moment is to convert HepMC3 to HepMC2.
It can be done with the following Python code:
import sys from pyHepMC3 import HepMC3 as hm if len(sys.argv) != 3: print(" Usage: converter.py input_file output_file") sys.exit(1) reader3 = hm.ReaderAscii(sys.argv[1]) if reader3.failed(): sys.exit(1) writer2 = hm.WriterAsciiHepMC2(sys.argv[2]) if writer2.failed(): sys.exit(2) event = hm.GenEvent() reader3.read_event(event) while not reader3.failed(): writer2.write_event(event) event.clear() reader3.read_event(event) writer2.close() reader3.close()

Thanks for the response. Indeed, switching to HepMC2 works fine.

The new release (3.5.0) contains the DelphesHepMC3 command that can read HepMC3 files.

Dear Delphes experts,
I'm experiencing the same problem as Meng mentioned. When trying to put hepmc3 event files from Pythia8 in Delphes-3.4.2, I get the error: invalid event format. Do you know how to fix this issue?
Kind regards,
Bob
