Hi Luiz,
You can modify your .h file:
- adding the necessary data members (background + signal) + idem for branches
- Modify the Notify function to compute the corresponding branch pointers.
- Modify the Init function:
-adding a call to Notify at the beginning
-testing if the branch is not null when setting the branch address.
In principle, I could modify the MakeSelector function to generate this type
of code, but I have to investigate possible side-effects when running with
chains.
