    Meta-search, Grid-Computing, and Machine-Learning – ASMS 2009 Poster

    June 1st, 2009, 11:25 am

    I’ll be presenting my ASMS 2009 poster “Improving the Sensitivity of Peptide Identification from Tandem Mass Spectra using Meta-Search, Grid-Computing, and Machine-Learning” on Wednesday, June 3, 10:30 – 2:30. This poster describes the use of, you guessed it, meta-search (many search engines via a single user-interface), grid-computing (lots of heterogeneous computers), and machine-learning (to reconcile the peptide identification results). The poster is available on the Edwards Lab publications page.
