                   Hi all 
                   I have a ntuple (recording events of simulation 
code)with the following structure 
                   1 ,2 , 3 and 4th raws are arrays of floats 
                   5th raw is float and last one is an array of floats. 
                   OK reading the ntuple is simple but I m interesting if 
in ROOT exists a comant or class that permits directly to obtain the mean 
values and sigmas of all recoreded events 
Cheers
