Hello, ROOters!
Would you be so kind to give me some explanation.
I am using program to create TTree where
SetAutoSave(1000000);
is set.
When looking output files inside root I am getting:
TFile** zee_tape.root Simple ROOT Ntuple
TFile* zee_tape.root Simple ROOT Ntuple
KEY: TTree isl;13 ISL test
KEY: TTree isl;12 ISL test
Why I have 2 keys?
I tried to see which is the difference (probably in wrong way)
between 2 KEYs:
TFile* f1 = new TFile("zee_tape.root");
TTree *a = (TTree*) f1->Get("isl;13");
a->Print();
Here I am getting normal print out and seems that
TTree has 120 000 entries.
Making after
TTree *b = (TTree*) f1->Get("isl;12");
b->Print();
It works fine, but it has 119639 events...
I guess that isl;12 is something left by Autosave,
but why it was not deleted?
Is it a normal behavior?
regards,
Elena
I am using ROOT Version 3.02/07 on Linux R.H. 6.1
