Hi! I have a problem with a TTree. How can i draw only EVENTID with instance 0 ? For example in the Event 14. Thanks!
‘instance 0’ is referring (likely) the first element of the array requested (here either TrueEallp or TrueE…)
So is it really your intent to get only the first element of those array that matches the criteria you gave (as the 2nd argument of the TTree::Scan)`
