Hi,
I was using TTreeReader to read a tree from produced Ntuple file. Where a quantity defined as array of second rank (i.e. vertex_Index[100][100]). To access array of rank one I can use TTreeReaderArray, But this is not working in second rank array.
Could you please suggest a method of accessing it by TTreeReader.
Thank you for your response. I usually using SetBranchAddress() class, but unfortunately for a high number of branches are call by SetBranchAddress() is very boring.
