R package bibliospec. R class to access ’sqlite’, ’BiblioSpec’ generated, mass spectrometry search result files, containing detailed information about peptide spectra matches. Convert ’Mascot’ ’.dat’ or e.g. ’comet’ ’.pep.xml’ files with ’BiblioSpec’ into ’sqlite’ files and than access them with the ’CRAN’ ’bibliospec’ package to analyse with the R-packages ’specL’ to generate spectra libraries, ’protViz’ to annotate spectra, or ’prozor’ for false discovery rate estimation and protein inference.
