How to choose shower program from generate_events?

Hi,

I do not know what a “.mg5” file is.

What you can do is the following
create a file with the following lines
> generate_events run_name
shower=Pythia8
detector=delphes
#you can include here all the line for the edition of the cards

then you can run those command with
./bin/madevent PATH_TO_YOUR_FILE

Cheers,

Olivier
