Hi, Changes in the way TTree works has broken some of my code. The changes are given below. Are these intended changes? I am using the very latest CVS updates on a RedHat 7.2 linux machine with a completely fresh recompile. 1. TTree::SetDirectory(0) does not seem to remove the tree from the current directory. Using the following script (and tree1.root from the tutorials directory), I get: { TFile f("tree1.root"); TTree *t1 = (TTree *)f.Get("t1"); t1->SetDirectory(0); gDirectory->ls(); f.Close(); t1->Scan(); delete t1; } TFile** tree1.root TFile* tree1.root OBJ: TTree t1 a simple Tree with simple variables : 0 KEY: TTree t1;1 a simple Tree with simple variables *** Break *** segmentation violation This did not use to happen in an earlier version (3.01/07) of ROOT. 2. When naming a TTree, it seems that the first argument cannot contain a space as illustrated with the following script. Is this the intended behavior? { TFile f("junk.root","recreate"); TTree *t = new TTree("tree data","T"); Float_t x; t->Branch("x",&x,"x/F"); x=2; t->Fill(); t->Write(); f.ls(); f.Close(); } Produces: TFile** junk.root TFile* junk.root Thanks for your help. Glen
