Hi Thomas,

It should be possible to just do
	tree->SetName("newname");
	file->Write()
However the original tree meta-data will still be present on the disk
and I am not sure you can safely remove it.

An alternative is to create a friend tree.
	new TTree("newname");
	tree->AddFriend(oldtree);
	file->Write();

Cheers,
Philippe.

Dear all,

is it possible to rename a tree in an existing file?

Thanks,
