Dear ROOTers,

I need to know how to condition a variable belonging to a branch of a tree
with a variable belonging to another branch.
For example: I ha a variable a belonging to branch A and a variable b
belonging to a branch B. I need for example, the spectrum of variable a
when b>0.
Any help will be appreciated
thanks
                               Giuseppe Pappalardo
