Missing .hep file when launching event using Pythia8 and Delphes

Asked by Stephen Roche

Hi experts,

I'm new to Madgraph, and have a question about some behavior I'm seeing.
I've been under the assumption from other tutorials and responses to questions here, that when I use Pythia8 and Delphes for my shower and detector respectively, that a .hep.gz file should be produced in Events/run_01 in the output.
However, I am only seeing a .lhe.gz file in this directory. Am I wrong in expecting to see this, or is there some mistake I've made?

Steps reproduced below:

./MG5_aMC_v2_6_2/bin/mg5_aMC
generate p p > t t~
output ttbar
launch ttbar
shower=Pythia8
detector=Delphes
done
done
cd ttbar/Events/run_01

I have confirmed that the correct paths to Delphes and Pythia are present in inputs/mg5_configuration.txt

Thank you.
Steve

Hi,

In principle it should be ok.
You should have more information on the screen why py8 is not run or in the py8 why it crashed if it run.

Cheers,

Olivier

Hi Olivier,

I was running this on lxplus when I had the issue.

I tried to reproduce the problem locally and everything worked fine, so there's probably some subtle issue with my setup on lxplus. Not a madgraph issue. Thank you!

Cheers,
