Dear Rooters,

I'm trying to automatically split a Tree with the option Splitlevel.
The code runs, but I get an empty file as output... so, I'm wrong
somewhere. Please help me to understand where! Here is the code:

   TTree *hdtt = new TTree("F","FINUDA HDT tree");
   hdtt->SetAutoSave(10000000);  // autosave when 10 Mbytes written

....

   TFndHdt *fndhdt;
   TBranch *b=0;
   Int_t bsize = 64000;
   Int_t split = 1;
   if (b) 
     b->SetAddress(fndhdt);
   else 
     b = hdtt->Branch("fndhdt","TFndHdt",&fndhdt,bsize,split);

........   (the fndhdt object is built)


   hdtt->Fill();    // within a loop on events

........



   hdtt->Write();   //  every 250 events and at end of run


Thanks in advance, 

        Piergiorgio
