Hi all, I'm having a problem using the GPS. I set a "Para" volume distribution which is confined to a portion of my detector. The particles are showing up in the right distribution, but they are not really randomized: the first vertex is always at the same point. I set the random seed in my main() in the standard way:
CLHEP::HepRandom::setTheEngine(new CLHEP::RanluxEngine); CLHEP::HepRandom::setTheSeed(time(0));
But this doesn't seem to have any effect. Does GPS get its random seed from some other source? Or do I need to manually set it somewhere via gps commands?
