Dear ROOT experts,
I have a root file with 1000 events and each event contains instances/particles (of total 3097) characterized by (momentum, energy, charge, …). I use these properties to predict individual particles using saved classifier (Scikit-learn python package) and the classifier outputs 3097 numbers of probabilitites. The problem is that I want to output a root file that contains the classification output with 1000 events not 3097. Is there any way to associate individual particles in each event to event number.
Thank you in advance
