Hi All

I can successfully run a pythia6 output file into my detector using Geant3 but the same when it try to do Geant4 does not work.

I do have Geant4 working and it all works if i just create a particle using fairboxgenerator and shoot it. But the problem only arises when i try to use pythia output as the input to my detector.

Here is the error message that root tells me (after telling me a lot about geant4)

### Run 0 start.
[INFO ] [09.07.2012 16:04:58] [FairPrimaryGenerator.cxx::GenerateEvent:170] FairPrimaryGenerator: (Event 1) 27 primary tracks from vertex (0.000000, 0.000000, 0.000000 ) Event Time = 0.000000 (ns)

I also dont know why those warnings are always appearing. So far i am just ignoring them and it seems that there is no problem.

Thanks for your help
Cheers
Raghav
