can someone give me a thorough exlpanation of the TTree - Entries structure? I already read something fro root-guide-v6 in Ch.12…
Is there a general rule or a given structure by which the events of an experiment are written inside the Tree?
Is the most basic method of accessing them this one?
[quote]Is there a general rule or a given structure by which the events of an experiment are written inside the Tree?[/quote]I am not quite sure what you mean or what you are looking for. The data stored in a TTree varies significantly from experiment to experiment and from user to users. What is it that you are trying to achieve?
and the manual as I mentioned.
I would like to understand the generic(or general or default) system/method that the TTree class uses to store data, i.e. in the simplest form of a TBranch: it can be type int or vector an so on…
Then what do we call an Entry?
So mostly I would ask far a link to a good description of that - and I sorry to mess around if this is obvious and in front of me but I cannot see it…
