Hello,
I want to run tree.cc example from Pythia8/rootexamples.I do the above:
make tree
./tree.exe
Then, pytree.root is generated:
root pytree.root
T->MakeClass(“blabla”)
And blabla.h+blabla.C are genarated.The problem is that there are no events stored at all!Why this happens?Am I doing something wrong?
