Hello ROOT Users,
I created a Root file which I was made from own data. But ı have a problem. I have 1 TTree and that’s name is “nominal” and I have 1 branch which called is jet_pt. I want to add 1 data which called is jet_eta but in the same Tree. When I add new data which called is jet_eta, Root file has 2 different Trees. But I do not want this. Just, I want 2 branches (2 leaves) at the same Tree. How can I make this?
