A New PEAKS Tutorial Video: Multi-Round Search

There are often many spectra which remain unidentified after a database search that have promising de novo sequences, leaving you wondering the source of these spectra.

  • remove spectra produced from contaminants
  • find endogenous peptides in a enzyme digested sample
  • refine search parameters to identify difficult targets
