Hello

I got a little problem. I  have produced more than a 100 files 
containing 2 ntuples (hbook format), all of them makes more than 1 
GBytes and I want to merge them in smaller  number of files in root 
format. Is it possible to do that in a easy way? I tried to modify the 
example "hadd.C", but whem compiling it, I got the message:

hadd.C:101: no matching function for call to `TTree::Add (TTree *&)'

(I just change the TH1 to TTree).

Thanks.

Luiz
