Hi,
I sometimes observe that when writing larger TTrees to a TFile, afterwards the corresponding key appears multiple times in the TFile, e.g.
(TFile *) 0x55f791612730
root [1] .ls
TFile** pid1M_loc_chi2.root
TFile* pid1M_loc_chi2.root
KEY: TTree ntp;3 ntpchi2
KEY: TTree ntp;2 ntpchi2
Why is it like this, and how can I avoid this?
Best and thanks,
Klaus
