Problem in using Pythia-PGS package with Mad5_v1_3_33

Asked by Shabbar Raza

Hi,
I am trying to use Pythia-PGS package with MadGraph5_v1_3_33. I have kept package in the same directory (i.e if MadGraph5_v1_3_33) and compiled it. I wanted to run pythia and pgs on my existing events. So I went to MyRunDir and made sure that I had pythia_card_default.dat and types the command:

./bin/run_pythia /home/shabbar/sw/MadGraph5/MadGraph5_v1_3_33/~madteam/pythia-pgs-for-mg 0 mt_T_173_Z2_unweighted_events.lhe.gz

but I am having the message that

No pythia_card.dat found. Quitting...

Since I have started using MadGraph recently have never used pythia with MadGraph so I am not sure how to handle this problem. It will very nice if you suggest some solution.

Thanks.

Hi,

did you do the following:
cp Cards/pythia_card_defaults.dat Cards/pythia_card.dat?

I think that this should solve your problem.

Cheers,

Olivier

Thanks Olivier for your suggestion. Yes, I have already tried it but had the same error message.

Hi,

I'm not sure at all since this version starts to be quite old, and
that part was deeply changed in 1.4.0
But could you try to launch that script from Events directory?

../bin/run_pythia /home/shabbar/sw/MadGraph5/MadGraph5_v1_3_33/
~madteam/pythia-pgs-for-mg 0 ../mt_T_173_Z2_unweighted_events.lhe.gz

Cheers,

Olivier

Hello Shabbar,

In v. 1.3.X, you need to run run_pythia from the Events directory:
cd Events
../bin/run_pythia PATH_TO_PYTHIA 0 RUN_PREFIX

But the easiest is to upgrade to v. 1.4.X, where you can simply use
bin/madevent
pythia run_name

All the best,
Johan
