Hi,
I am opening a TFile
root [0] TFile f1("data.00.1.root");
which is converted from an hbook file containing one ntuple with ID 1.
For some reason (for which I find no reason in my fortran/hbook code)
have two keys in the root file:
root[1] f1.ls()
TFile** data.00.1.root HBOOK file: data.00.1.ntp converted to
ROOT
TFile* data.00.1.root HBOOK file: data.00.1.ntp converted to
ROOT
KEY: TTree h1;2 ORANGE
KEY: TTree h1;1 ORANGE
Now I have several files or rather ntuples which I want to chain - no
problem in paw with the hmerge command. But in root the TChain fails maybe
because some of the fails only have one KEY: TTree entry:
TFile** data.00.3.root HBOOK file: data.00.3.ntp converted to
ROOT
TFile* data.00.3.root HBOOK file: data.00.3.ntp converted to
ROOT
KEY: TTree h1;1 ORANGE
Any suggestion what I might do? I was thinking about saving one of the
versions (I understand the h1;1 and h1;2 stand for different versions?) to
a new file ... but I had some difficulty in doing so ... Can anybody help?
Cheers, and thanks,
Thomas
