Thanks, Jacek.
I followed what RootDoc.html says but I still have the following error:
root [0] .L Myclass.C
root [1] TFile *f = new TFile("jay.root","RECREATE");
root [2] TTree *mytree = new TTree("MyT","Event Tree");
root [3] event = new Event();
root [4] Int_t bufsize = 256000;
root [5] Int_t split = bufsize /= 4;
root [6] mytree->Branch("event", "Event", &event, bufsize,split);
Error in <TTree::BranchObject>: Cannot find class:Event
It seems not to recognize my class Event. Do you have any idea?

Thanks,
Jayoung
