So, I am trying to examine ppbar->D0-antiD0->K-pi+ K+pi-

The momentum is 8 GeV/c...10000 events...

I want to do some basic analysis, kinematics and so on..
So for example I want to draw psi4160 mass..
In the last for loop for the psi4160 I want to take column "psi4160m" and draw it...
The problem is that the ntuples I get from this analysis are empty in the "psi4160.root" file...
They exist but they are empty...So I guess there is a problem writing/filling the tuples..
Any ideas???
You can find the macro attached...
You will probably find some mistakes in the macro but I don't think they affect the filling/writing procedure...

Thanks
