Hi Jayoung,
TFile::ls shows the name of teh file and its title, the the name and title
of its sub directories. In case you have no subdirectories (your case),
ls still prints the name of the directory.
In your file, however, you have two copies of your Tree EVENT.
Did you write it twice ? May be you have TTree::SetAutoSave active ?
