Dear MadGraph5_aMC@NLO support,
I am generating pp > zz [QCD] events, decaying with Madpin and hadronizing with Herwigpp. However, before entering the showering phase, my jobs are crashing with the following message:
InvalidCmd : No matrix elements generated, check overall coupling orders
Do you know how to solve this issue? I'm using version v2.1.0 of MadGraph5_aMCatNLO.
Thanks!
Ines
P.S.: I'm pasting below the relevant lines from the log file:
