MsQuality - an interoperable open-source packagefor the calculation of standardized quality metricsof mass spectrometry data

MotivationMultiple factors can impact accuracy and reproducibility of mass spectrometry data. There is a need to integrate quality assessment and control into data analytic workflows. ResultsThe MsQuality package calculates 40 low-level quality metrics based on the controlled mzQC vocabulary defined by the HUPO-PSI on a single mass spectrometry-based measurement of a sample. It helps to identify low-quality measurements and track data quality. Its use of community-standard quality metrics facilitates comparability of quality assessment and control (QA/QC) criteria across datasets. AvailabilityThe R package MsQuality is available through Bioconductor at https://bioconductor.org/packages/MsQuality.
