[Gate-users] Problems with Root Output: Hits;9 Hits;10

[Didier Benoit]

Hi David,

Do you create 1 ROOT file for your total simulation?
If yes, could you try to split your simulation, and to create a ROOT 
file for each run, I never had your problem by this way. Tell me it works.

Kind Regards,
Didier
