Hi
I'm trying to Merge about 100 root files (with 2 ntuples) into
fewer files. I'm following the Brun's advice:
root> TChain chain("h1")
root> chain.Add("fil*.root")
root> chain.Merge("outfile.root")
But most of the time, when I give the 2nd command, root answer nothing,
that means, it doesn't read the files, so I repeat the command and SOME
TIMES it succeed to read them. To give the command chain.ADD again, I
MUST get out of root, since giving this command twice, it get a
segmentation violation. Loot the output below.
root [0] TChain
chain("h1")
root [1] chain.Add("wphact20cc_e206.7_c1*.root");
root [2] chain.Add("wphact20cc_e206.7_c1*.root")
(Int_t)0
root [3] chain.Add("wphact20cc_e206.7_c1*.root")
*** Break *** segmentation violation
Root > .q
In fact, I had to kill the process since even the ".q" did not work.
What is going on? What am I doing wrong?
I'm using the "official" version at CERN (Version 3.01/06 12 July
2001).
Thanks
Luiz
