title: Response to: the problem with peptide presumption and low Mascot scoring.
abstract: A letter published in January 2011, "The Problem with Peptide Presumption and Low Mascot Scoring", raised concerns about the reporting of peptide identifications based on mass spectrometry data with high precursor mass accuracy. We explain why we believe these concerns are unfounded.
