I have a question concerning RDataFrame snapshotting behaviour from a TChain.
Let’s say my pseudocode is :
TChain ch("tupleName"); for f in files : ch.AddFile( f) ROOT::RDataFrame df( ch) df.Filter.Snapshot().
I see some weird behaviour when
contains a TTree with tupleName and say 100 branches
and file contains 100 + 4 branches.
For some reason the snapshot contains entries only from file.
Is that expected?
What is the procedure to ensure this to not happen, without having to “manyally” add aligned branches names for the 2 files?
