Dear Anna,
you're right. Please replace the according statement with
fRun->SetGenerator(pythiaGen);
and comment lines 48/49. The primary generator is being created inside already.
Cheers!
Ralf

Dear Ralf,
Thank you! It started to work when I commented the lines 48/49 and replaced fRun->SetGenerator(primGen); to fRun->SetGenerator(pythiaGen);
and commented also the line primGen->AddGenerator(pythiaGen);
But then I faced the problems with the further usage - tut_aod.C. I have to think about this and shall report it later.
Cheers,
Anna

Dear colleagues,
I found more information about possible launch of PYTHIA simulation from inside Root - fairsoft_may18/tools/root/montecarlo/pythia6.
From the file /src/TPythia6.cxx one can see how one can choose and set the internal PYTHIA parameters about which I was confused.
So one can really call PYTHIA from Root using the presented parameters. The problem is that the presented list of common-blocks is not full and some
very important parameters which allow to run PYTHIA at low PANDA energies are absent (by default it doesn't work). I hope that inserting the missed information could be done in
analogous way as for the other common-blocks. But one have to think how to compile then these all together.
Best regards,
Anna
