Hi,
I am trying to add aprocess generated by pythia in a tree. I want to list variables like Pt, E etc in a NTuple named '‘data’. But with that I want to add number of events generated (Nevents) in the process in same NTuple.
Of course number of entries in Nevents and all other variables like Pt, E will be different and it is giving me error while combining these two things.
I have posted previous question but it was for TTree and not for TNtuple. Is it possible to add such things in same NTuple?
-------This was using TTree---------------

Also please check attached file. That is what I want to produce using NTuple.
Thank you.
