I got a problem with setting up my TTree, maybe someone can help.
What I want to do is to produce a Tree with Branches that are created from classes that basically look like this:
Where the Branch is created from BunchofDetectors. This works just fine. The Problem is, that normally most of the Detectors are empty and i don’t want to write lots of 0s for each event.
Therefore, is It possible to:
A: Disable subbranches when filling the tree in any way without loosing the correct event numbering.
(SetBranchStatus does not work)
B: Define LotsOfData as variable length array, that changes its length on a event-to-event basis without getting the “TStreamerInfo::Build: discarding: Int LotsofData, no [dimension]” Error.
Many thanks in advance,
