Yes. You are right. Any idea how I can do the cut and obtaining a new TTree? Or is this impossible?
Never mind. Thank you anyway for your support.
You try to change the internal structure of the tree (going from a “table” to a “variable”), so no simple “CopyTree” will do the job.
Ok. I understand. Is it possible to get a TTree back from a TEventList (since TTree::Draw is capable of storing its result in such a structure)?
I think TEventList will return the list of tree entries (so again, whole events, like “CopyTree”).
I guess you might be interested in “How to obtain more info from TTree::Draw” in the TTree::Draw method description.
Ok, it seems to be unavoidable to iterate the tree manually and copy all leafs into a new tree. Thank you for your patience.
