Hi Mamen,

without hands on the n-tuple (or the root-files) itself, it's hard to find a diagnosis for your problem. According to your table you again have a discrepancy between Project() (1st column) and summing yourself (3rd column), what I don't understand. To reset the histograms you might better use TH1F::Reset(). I don't know exactly how (or whether) the bin weights influence the number of entries.

Best,
Klaus
