TTreeReader for 2d array

ROOT
1

Dear experts,

I was wondering if there is any way to read a 2D array branch using a TTreeReader. I found some relevant questions since 2019. It seems that at the moment it was not supported. Is it now?

thank you,
Panagiotis

Hi @panagiotis_bellos ,

this must have fallen through the cracks, sorry about that! Depending on the exact schema of your TTree it might be possible to read the 2D array as a flattened 1D array. Some cases are simply not supported.
This is something that we plan to fix in the future.

@Axel might be able to comment with more authority.

Cheers,
Enrico
