Assess the contribution of the targeted precursor in fragmentation acquired or anticipated isolation windows using a metric called "precursor purity". Also provides simple processing steps (averaging, filtering, blank subtraction, etc) for DI-MS data. Works for both LC-MS(/MS) and DI-MS(/MS) data. Spectral matching of fragmentation spectra can also be run against a SQLite database of library spectra.
