		Dear Colleagues, 
I try to use generated events, generated with PYTHIA6 
I produce ascii txt file in ~/pandaroot/pgenerators/Pythia6 
(name is genevent1.txt in attachment). 
Then I change my code according to advice done in: 
http://panda-wiki.gsi.de/cgi-bin/view/Computing/PythiaGen6 
 
add lines: 
  gSystem->Load("libPGen"); 
  PndPythia6Generator* pythiaGen = new PndPythia6Generator("genevent1.txt"); 
  primGen->AddGenerator(pythiaGen); 
 
run code but I've got an error message: 
==================================================================== 
 
### Run 0 start. 
[INFO   ] FairPrimaryGenerator: (Event 1) 0  primary tracks from vertex (0.000000, 0.000000, 0.000000 )  Event Time = 0.000000 (ns) 
 
    TG4PrimaryGeneratorAction::TransformPrimaries: 
    No primary particles found on the stack. 
*** TG4Exception: Aborting execution *** 
 
What could be wrong? 
Best Regards, Yuri.
