tree->Print() does not produce any output

Hello

I am not able to see the output of TTree::Print() inside the root interpreter. Does it mean I am filling the tree wrongly?

You can have a look at the example tree that I uploaded:

Sidenote: In particular I am interested on knowing how much disk space each leaf takes. I am producing very big root files now and I would like to know where I am consuming most of the space…

Thank you

Marcos

[...]$ rootls -l -t yourfile.root
