Dear roottalkers!
I have multiple root files with ntuples,
and I would like to know is there a way to merge them into one big root
file.
The TChain::Merge() method does not work.
It merges chains but zeroes out the content of all ntuples.
A macro presented in the tutorial
http://root.cern.ch/root/html/examples/hadd.C.html
merges histograms, but not ntuples.
Maybe there is a trick in invoking Merge().
I would appreciate if someone could answer this.
thanx!
Artur Vaitaitis
