Hadd can't merge files successfully

ROOT

Dear ROOT expert:

I tried to use hadd to merge two files in
data11_7TeV.00191933.physics_Muons.merge.NTUP_SMDILEP.f415_m1025_p833_tid622052_00/
but it does not go on smoothly, no matter with ROOT 5.28 or ROOT 5.32:

[valtical04] /work/users/qing/dq2 > hadd test.root
data11_7TeV.00191933.physics_Muons.merge.NTUP_SMDILEP.f415_m1025_p833_tid622052_00/NTUP_SMDILEP.622052._000233.root.1

Problem still exists after sourcing the ATLAS enviroment:

[valtical04] /work/users/qing/dq2 > export
AtlasSetup=/afs/cern.ch/atlas/software/dist/AtlasSetup
[valtical04] /work/users/qing/dq2 > source
/afs/cern.ch/atlas/software/dist/AtlasSetup/scripts/asetup.sh
17.3.1.1,AtlasProduction,setup,here

Any idea how to avoid such warnings or errors?

Cheers,Gang

Hi,

hadd needs to be able to load the library corresponding to the custom objects (and they would need to implement the Merge function in order to be mergeable) ; for this ATLAS would need to provide ‘rootmap’ files for its library.

You may also want to check whether the file where produce with a version of ROOT more recent than the one you are using.

Cheers,
Philippe.
