In lindsaypino/MSstats-patch: Protein Significance Analysis in DDA, SRM and DIA for Label-free or Label-based Proteomics Experiments

Description

A set of tools for protein significance analysis in SRM, DDA and DIA experiments.

Details

Package:	MSstats
Version:	3.7.3
Date:	2017-01-16
License:	Artistic-2.0
LazyLoad:	yes

The package includes four main sections: I. explanatory data analysis (data pre-processing and quality control of MS runs), II. model-based analysis (finding differentially abundant proteins), III. statistical design of future experiments (sample size calculations), and IV. protein quantification (estimation of protein abundance). Section I contains functions for (1) data pre-processing and quality control of MS runs (see dataProcess) and (2) visualizing for explanatory data analysis (see dataProcessPlots). Section II contains functions for (1) finding differentially abundant proteins (see groupComparison) and (2) visualizing for the testing results (see groupComparisonPlots) and for checking normality assumption (see modelBasedQCPlots). Section III contains functions for (1) calculating sample size (see designSampleSize) and (2) visualizing for the sample size calculations (see designSampleSizePlots). Section IV contains functions for (1) per-protein group quantification and patient quantification (see quantification)

Examples of data in MSstats are (1) example of required input data format from label-based SRM experiment SRMRawData; (2) example of required input data format from DDA experiment DDARawData; (3) example of required input data format from label-free SWATH experiment DIARawData.

The functions for converting the output from spectral processing tools, (1) Skyline, SkylinetoMSstatsFormat, (2) MaxQuant, MaxQtoMSstatsFormat, (3) Progenesis, ProgenesistoMSstatsFormat, (4) Spectronaut, SpectronauttoMSstatsFormat, and (5) Proteome discovere, PDtoMSstatsFormat are available.
