Hello,
listing the content of the root file I’ve just produced , I don’t understand why the TTree object T is on file twice with two different cycle numbers (what is a cycle number?) while I have written it only once (tree->Write()).
root [1] f = new TFile(“BuildBeautyPb_1.0.root”)
(class TFile*)0x8bd2908
root [2] .ls
TFile** BuildBeautyPb_1.0.root
TFile* BuildBeautyPb_1.0.root
KEY: TTree T;12 Heavy flavor tree
KEY: TTree T;11 Heavy flavor tree
Any pedagogical explanation?
Many thanks
Regards
Rachid
