I have quite a big root file (1.5GB) with many events and as a first task I was asked to filter the events so they all will be within a specific energy range. My question is where should I read in order to know how to do it?
I’ve found a few guides and tutorials, and if I had the time, I would start at the beginning. Unfortunately, I don’t so I ask for a more specific reading material.
Thank you very much for the informative and fast reply.
I guess I will start at the first link but will read the “ROOT primer” before going on to the next links.
