QuickMod is a spectral library search based MSMS data analysis tool, designed to identify modified peptides. The QuickMod algorithm assumes that the precursor mass difference between a query spectrum and a candidate library spectrum can be explained by a modification. Based on this assumption the two spectra are aligned and the fit of the spectral alignment is assigned a similarity score. In a second step the most likely attachment position of the modification is determined.
