A fully automated, user-independent method is described for computer-mediated interpretation of data derived by mass spectrometry of an experimental peptide to identify and characterize a corresponding peptide sequence in a peptide database. The method identifies the corresponding sequence if it is present in the database, without the need for a skilled observer to choose from amongst a list of possible matches. By using an automated back-read process, the present method can uniquely identify a corresponding peptide sequence in a database based on a single matching peptide sequence. The method also permits mapping of mass spectral data to sequences in peptide or nucleotide databases for unambiguous identification of exons; determining a correct reading frame; identifying artefacts and errors in sequences; identifying mutations and polymorphisms; identifying post-translational modifications; and identifying exon-intron boundaries.
