Hi Iouri,
To copy them with selection, you are going to add code like:
origFile->cd("DB");
t = (TTRee*)origFile->Get("Dbname");
newFile->mkdir("DB"); newFile->cd("DB);
t->CopyTree(....);
For all the directories and trees (STNTUPLE, DB, FillStntupleFolder,
InitStntupleFolder, StntuipleMarkerFolder).
You might also need to do the same for the histograms (see
$ROOTSYS/tutotials/hadd.C for some inspiration).
Cheers,
Philippe.

Hi Philippe,
Thank you very much for your answer. You are right.
I cloned only STNTUPLE and did not clone the DB file to new root file.
Do you know how one can copy (with selection) all files from STNTUPLE file
(STNTUPLE, DB, FillStntupleFolder, InitStntupleFolder,
StntuipleMarkerFolder)?
With best regards, Yuri
