RooDataSet crash importing TTree with vector branches

Roofit and RooStats

Hi, all,

I got crash when I create RooDataSet out of TTree with vector branches. I can’t find any interface to be suitable for vector tree. Can I use RooDataSet with vector tree?

Thanks,
Woochun

Dear Woochun,
I am not an expert, but as far as i know it should be not possible import data from structured branches because RooFit datasets are designed to be ‘flat’.
Cheers,
Valentina

Hi,

I confirm that. You can only import scalar variables from a tree
