Adding multiple files to TChain

Hello all,

I am doing a simple procedure of adding multiple files with same tree structure to Tchain. Something like
TChain fad(“FADu”);

but after all the addition “fad” has spurious entries like 10e-314 or 10e214 something like that ? I have checked individual file they are fine. Is there a work around ?

I have another quick question, is it possible to draw after ignoring duplicate events

there are multiple entries for the same FADbkg value.

thank you in advance
