Hi - Is it straightforward to have variable-length branches in a TTree? I would like to have functionality a la HBOOK CWN's, i.e. a branch which has a leaflist like: "N:x[N]/F:y[N]/F:z[N]/F" etc. where i point the branch to a structure defined somewhere: { Int_t N; Float_t x[32]; Float_t y[32]; Float_t z[32]; } The point is that when I set N to 10, then only 10 x,y,z's will be filled in. I am somewhat of a novice with trees, so this may be simple, but i have been unable to make anything work.
