MR-MSPOLYGRAPH / MSPolygraph 1.61

:: DESCRIPTION

MR-MSPOLYGRAPH is a MapReduce based implementation for parallelizing peptide identification from mass spectrometry data

MSPolygraph is an open source hybrid database and spectral library MS/MS search engine that runs in either serial or parallel modes. MSPolygraph examines the ions in MS/MS spectra to identify likely matching candidate peptides from a reference database of protein sequences (.Fasta file). MSPolygraph also supports searching a spectral library (collection of annotated MS/MS spectra).
