Hi Thierry, TTree::CloneTree creates a new TTree object. This new object is automatically added to the list of objects associated to your current directory/file. This object will be automatically deleted when you close this directory/file. You can delete this object in your class destructor if you do not need this object before you close the file. use gDirectory->ls(); to see the list of objects in your current directory. use gObjectTable->Print(); to see the total number of objects per class Rene Brun
