I included in attachment the skeleton program generated by MakeClass. I
noticed that there are much less branch addresses set up than the number
of branchs/leaves (in case it has been split) that exist on the tree.
---------------------------------------------------------------------
I sent this message yesterday and got no reply. I checked the roottalk
rules and I do not think this messages is not in accordance with them,
so I'm posting it again, since I need urgente help because I need to get
some result till monday.
Thanks in advande for you help.

Hello
I have a Tree with several branches and inside them, also several
leaves. This tree has not been written by me, but I have to analyse it.
I generated a skeleton code (using both MakeClass and
MakeSelector), but I could not access the data I want with the code root
gave me. I can draw the variable using tree->Draw("branch.var"), but when
trying to access them inside the skeleton program, it fails. I realized that
on the header file, the variables are defined like
branchname_var
(with an underscore), that means, it do not seem to be a structure like
object.
I tried several variation of statements and all of them failled.
Do I need to add more (accessing) code to be able to read the data, like
setting branch /leaf address? I mean, apart from the the code particular
to the my analysis? I guessed
that MakeClass and/or MakeSelector should write a skeleton ready to
access the data.
I took a look on the root pages and found nothing conclusive, since all
the instruction seems to be related to unamed macro. I also downloaded
the new
User Guide and it did not help me too.
Other information:
Root version: 3.05/03
OS : Linux Red Hat 8.0
In attachment it is a file describing the ntuple variables, since the
tree is too big and I cannot generated a smaller one. The important
branch for me is one starting with ELE (for eletrons) and ending with p_off:
p -> means physics information (d stands for debug information)
off -> off line processing.
Thank you.
