[ROOT] filling selected branches of a tree.

 I have a seemingly simple problem. I have a tree containing two branches 
and I will only fill one of them ignoring the other branch. If I use only 
branch->fill it doesn't update the tree (tree has zero entries, file 
contains no data).

If I use tree->Fill it seems to try to fill the whole tree. 

So my solution would be to try to use tree->Fill but to force it to ignore 
one of the branches.

Is this possible ? Any other suggestions ? Should the branch->Fill work ?

Thanks in advance,
