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:

add lines:
PndPythia6Generator* pythiaGen = new PndPythia6Generator("genevent1.txt");

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)

No primary particles found on the stack.
*** TG4Exception: Aborting execution ***

What could be wrong?
Best Regards, Yuri.

I have seen that in your file you have floating numbers with D instead of E. I am not sure if this can be digested by fscanf and how.

I have opened your .txt file and substitute with emacs all the D with E... and I could run your file.

The problem was in the "format". I have just updated in svn the example.f with the correct syntax.
