Hi All,

I have a program that creates a root file with an Event branch. The branch
is split so opening the file in root I can Draw the variables inside Event
just doing (assume that in Event there is: double energy;)
atree.Draw("energy")
Is it possible to do a similar thing with SetBranchAddress? I mean to use
the split variables as if they weren't in a class?
Something like this:
double energy;
atree->SetBranchAddress("energy",&energy);
atree.GetEntry(10);
I tried this approach, but the energy variable doesn't change.

Thanks is advance.
Ciao, Daniel.
