Krönik filters, validates, and summarizes peptide features identified with Hardklör from data obtained during liquid chromatography mass spectrometry (LC-MS). Hardklör and Krönik were designed to rapidly identify peptide and protein features in high resolution spectra of complex mixtures. These algorithms were developed to meet the demands of modern mass spectrometers that are capable of generating large amounts of robust mass spectrometry data. Spectra containing tens to hundreds of overlapping ion signals are reduced to a relevant list of observed monoisotopic mass values, charge states, and signal intensity values when using Hardklör. These features are then filtered, validated, and summarized by using Krönik for the analysis of liquid chromatography mass spectrometry (LC-MS) data.
