Hi Jan,
Your Tree contains more than just the two branches for which you set the
addresses. If the Tree has been created with something like
MyClass *obj;
tree.Branch("top","MyClass,&obj);
in the reading program you have to do:
MyClass *obj=0;
tree.SetBranchAddress("top",&obj);
you cannot set the addresses of the sub branches only if you call
t1.GetEntry to read all branches.
