Hi,
I have a bunch of root files each contain a Tree called “Nominal”, some of them has 0 entry, I merge all of the output root files using “hadd -f”.
My problem is when I try to print the content of the merged root files I got something like this
root [1] Nominal->Print()
******************************************************************************
Tree :Nominal : Nominal
Entries : 3216510 : Total = 329 bytes File Size = 194
: : Tree compression factor = 1.00
******************************************************************************
without any branch printed.
My assumption is that somehow the merged root file got affected by the root files with 0 entry. I would be grateful if you could help me solve this ?
Thanks
