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 as well
as a very simple gWidgets based GUI to fill out a msgfPar object.
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.
MSGFgui and it's sister package MSGFplus is intented for inclusion within the next Bioconductor release. Until then, try it out by installing as follows:
source("http://bioconductor.org/biocLite.R")
biocLite('mzR')
biocLite('mzID')
install.packages('shiny')
install.packages('devtools')
