Dear all,
I would like to merge several root files containing histograms. However, I would not like to merge some of the histograms. The structure of the files is schematically presented below.
I would like to merge all the histograms in “folder1”, while ignoring histograms outside “folder1”, which are all the same in all the files.
File
|___ folder1
~~~~|__ histogram2
~~~~|__ histogram3
|__ MetaData_EventCount
|__ cutflow1
|__ cutflow2
Is something like this already possible to do with hadd?
Best,
Miha
