Hi,

you might want to have a look at Seed, http://www-d0.fnal.gov/nikhef?seed
It helps in "objectifying" data stored in ntuples.

The "basic" option is TTree::MakeClass, see
http://root.cern.ch/root/TTree.html
It creates source code with which you can read ntuple data into a struct
(i.e. no real objects).

Cheers, Axel.
