This package is for version 3.8 of Bioconductor; for the stable, up-to-date release version, see msPurity.

Automated Evaluation of Precursor Ion Purity for Mass Spectrometry Based Fragmentation in Metabolomics

Bioconductor version: 3.8

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.
