Whizard seems to code the flow as:

  • flow1, flow2 (2x IntAttribute)
  • HepMC3 specifies: flows as VectorIntAttribute)
    According to https://arxiv.org/pdf/1912.08005.pdf Section A2 HepMC switched to the VectorInt at v3.2.0.
    KEY4HEP is at HepMC3.2.7, need to check with Whizard.

#26 removed the color flow as the MCParticle in EDM4HEP will no longer carry this information (discussion with HepMC) authors, therefore the issue is resolved
