Dear ROOTers, I'd like to understand and learn how to create a tree with an array branch. I read the Tutorial section (tree3.C). But why does the ff. line produces a segmentation problem/error messages: -------------------------------------------------------- ........ int TOTAL = 2; float AA[TOTAL]; TTree * tree = new TTree("tree","What a nice Tree"); tree->Branch("AA",AA,"AA[TOTAL]/F"); ...... -------------------------------------------------------- Pls see URLs: http://neutrino.kek.jp/~zaldy/root_work/MyRootFaq/Report_Branch_Array_Arg.txt http://neutrino.kek.jp/~zaldy/root_work/MyRootFaq/test.cc while: --------------------------------------------------------- ......... float AA[2]; TTree * tree = new TTree("tree","What a nice Tree"); tree->Branch("AA",AA,"AA[2]/F"); -------------------------------------------------------- dont. Am using ROOTV: 3.04/02 gcc 2.91.66 Thank you. -------------------------------------------------------- Zaldy A.
