Hello rooters, I have to chains, which should contain the same files, I tried: ------ TChain c1("Events"); // Tree containing 1000 Events c1.Add("file1.root"); c1.Add("file2.root"); TChain c2("RunHeaders"); // Tree containing one event c2.Add(&c1); ----- c2.GetEntries() results in 1000 instead of one and reading results in reading "Events" instead of "RunHeaders". I tried the following, too, and this worked: ------ TChain chain("RunHeaders"); TObject *obj; TIter N(c1.GetListOfFiles()); while ((obj=N())) c2.Add(obj->GetTitle()); ------- What is the idea of TChain::Add(TChain *) if not to add all files from one chain to the other chain? Thanks, Thomas.
