Quantitative features for mass spectrometry data

What is QFeatures?

QFeatures is a Bioconductor package that provides infrastructure to management and process quantitative features for high-throughput mass spectrometry assays. It provides a familiar Bioconductor user experience to manage quantitative data across different assay levels (such as precursors, peptide spectrum matches, peptides and proteins or protein groups) in a coherent and tractable format.

If you are familiar with the MSnbase package, QFeatures could be summarised with:

Evolving MSnSet data towards SummarizedExperiment, but for MS data.

Getting started

The QFeatures class is used to manage and process quantitative features for high-throughput mass spectrometry assays. See the QFeatures introduction to get started and the Processing quantitative proteomics data with QFeatures vignette for a real-life application. Visualisation of quantitative mass spectrometry data contained in a QFeatures object is illustrated in the Data visualisation vignette.
