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. We call these ‘de novo only spectra’. Multi-Round search gives you the ability to further analyze only these spectra. This helps you:

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