DelphesHepMC: No such file or directory

I will discuss this with Pavel and check the version that we advise to use to fix the problem.
An easy fix is likely to add a symlink and define DelphesHepMC as DelphesHepMC2

Cheers,

Olivier

Thanks! To ensure, the 2 can be used interchangeably, right?

I'm not a Delphes author but I would bet no.
My guess is that one should be used for hepmc2 and one for hepmc3 input file.

Hello, I haven't sat down to add the symlink yet but I was wondering if Pavel has responded? For further context on the Delphes version I used the one linked from this post: https://cp3.irmp.ucl.ac.be/projects/delphes/ticket/1579

Thanks,
