filter peptide indentifications in .pep.xml file from sorcerer

[alessio maiolica]

Hi everyone,
is there a way in the TPP, to filter a .pep.xml file in other  to keep ONLY  the  hit  with the highest score ?
As in the example below I would like to eliminated all the other peptide identifications except teh one with the highest score.

thanks
alessio
