Problem cloning a branch casted to a tree

ROOT

Hi,

Im trying to use the CloneTree function to copy the structure of a branch. The branch is first casted to a tree just for this purpose. But… it fails (a huge error message, starting as below). Isnt this possible? Can I do it some other way?

thanks

What does it mean “casting a branch to a Tree”? This does not make sense.
If you want to copy a subset of a Tree to another Tree see tutorials $ROOTSYS/tutorials/tree/copy*
