Hi Sheila,
the number of entries is (in the standard package) the number of
selected events. This means at least a good best B candiate and a lepton
candidate. Maybe the lepton candidate must exceed 1 GeV in momentum. But
the number of entries should be below or equal the number of events in the
tcl file. So I guess there is something wrong. How is the rest looking?
Cheers,
Wolfgang
