Important Object Ownership Management
GeneralROOT will help you manage some objects, but others should be managed by yourself. When a histogram, a TTree or a TEventList is created, it is added by default to the list of objects in the c... -
ROOT File .root

Executing Macros or Functions
Easy ways: 1$ root MacroName.C 1root [0] .x MacroName.C (sometimes .so is also available. See here .) Or you can load macro first and use function in it: 12root [0] .L MacroName.Croot [1] MacroNa... -
Naming Conventions and General Variables
