Open xAOD file in SWAN

Software

Hello,

Does anyone know if it’s possible to open xAOD files in SWAN?

Thanks

Yep, it sure is. FWIW, it’s also one of the ways folks can use the ATLAS Open Data.

Did you try something and find that it isn’t working?

Hi !I am trying to do a bit of exploration for some CaloTopoClusters (xAOD::CaloCluster) but I can’t load the ATLAS dictionaries (code below gives an error):
import ROOT
ROOT.xAOD.Init().isSuccess()

I tried to use some bash magic cells to setup AnalysisBase but it still does not work.
Any help would be greatly appreciated!
Thanks

Hi @gtarna ,

Since there xAOD objects, do you need the dictionaries? They should all be readable in vanilla ROOT.

Best,

Zach
