selecting events

I know how to select a number of events by making an empty tree:
TTree *select_tree=fChain->CloneTree(0)
and then filling that tree with                                                                                 


and wirte it in a file                                                                                 

TFile f1("selection.root", "RECREATE");


Now the problem is that I have about 15 ntubles( about 6 GB totally) and the job crashes in between . Is that any way to write the selected events in more than one root tuple. (the shortest way) called for example selected_tree1.root , slected_tree2.root and so on.                                                                                 

Many Thanks,
