[ROOT] Scanning a ROOT file

Hi,

    Is there any way to scan a ROOT tree and count the entries that satisfy some user cuts?

    The command below scans the tree and prints the results 25 entries each time, but what I want
is to avoid the printing and just go through all the entries without stopping every 25.

     myTree->Scan("i_id1:i_id2","i_id1!=-1 && i_id2!=-1 && i_id1==0");

    Is there any variation of this?

    Thanks!

Stelios.
