MSGFplus

Release: Devel:

This package aims to bridge R and the peptide database search tool MS-GF+. The main class of the package is msgfPar which handles parsing of parameters to MS-GF+. The msgfPar class has a runMSGF method that starts a peptide search for a given set of MS data files and possibly reimports the results using mzID.

Besides this basic functionality it also supports reading in parameters from mzIdentML files created by MS-GF+ in order to replicate a search setup.

MSGFplus is intended as a pure R wrapper. For a more engaging user experience have a look at MSGFgui which provides a visual interface on top of this package using shiny.

Installation

MSGFgui and it's sister package MSGFplus are part of Bioconductor and can be installed through that repository. Instruction are as follows:

if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
BiocManager::install('MSGFplus')

Credit

Sangtae Kim is the developer behind the MS-GF+ algoritm, without which this package would be rather shallow. Furthermore he has provided fast and helpful feedback during the development process.
