I have a tree with one branch ("T") into which I populate with TClonesArray of objects of class CL: Class CL : public TObject { public: double f1; double f2; int f3; int f4; .... }; The split is set to 1 when the tree is filled with data. Now, I want to read data from the resulting root file. As in the tcl.C example, I do the following: TClonesArray *arr =0; tree->SetBranchAddress("T", &arr); tree->GetEvent(event_number); This will extract data for f1, f2, f3, and f3... (all data fields defined in class CL.) Suppose I want only f1, and f2. What is the best way ? --HP
