Hello!

I've tried the setSeeds method and it works Very Happy

I checked the g4Config.C , the option "stepLimiter+specialCuts+specialControls" is setted. If I looked to:-I- PndStack: the Total number of particles is changing according to my cut.

But if I look to the output it's always the same.

Could you explain me why?
