Hi all,
I’m trying to merge files with the exact same folder/histogram structure, but hadd fails leaving me none the wiser, can someone clue me in on what might be wrong…
mdj@hepmac-mdj output> hadd -f final.root output1.root output2.root
Target file: final.root
Source file 1: output1.root
Source file 2: output2.root
Target path: final.root:/
Cannot merge object type, name: Analysis title: Analysis Folder
I use the following elements: TFolders, TH1, TH2, TH3 and TProfiles, nothing else for now.
The first level directory structure (TFolders can contain other TFolders with histograms and TFolders…):
mdj@hepmac-mdj output> root output1.root
root [0]
Attaching file output1.root as _file0…
root [1] _file0.ls()
TFile** output1.root
TFile* output1.root
KEY: TFolder Analysis;1 Analysis Folder
root [2] Analysis.ls()
