Hi Rooters,
I am trying to merge trees of the same kind which sit in different (smaller) files into one.
Sorry, I know this issue has already been proposed in the past but I was not able to find the reply to noeding (<merging root files>, Fri May 28, 2004 14:04).
I use a TChain and:
m_The_Chain->Merge(FileToWriteFinal,100000,"C");
crashes, while
m_The_Chain->Merge("AllTheTrees.root");
gives me a final file whose size is roughly one hundred times bigger than
the sum of the initial smaller files.
I have tried both with uncompressed and compressed (level 9 files).
I tried with several releases, for instance v4.02.00/rh73_gcc296/.
What am I doing wrong?
Thanks, regards, Giovanni Received on Fri Feb 18 2005 - 17:47:09 MET
