This video introduces the major new features provided by PEAKS X. In PEAKS X, a new peptide feature based approach to de novo sequencing and protein identification has been added, breaking the assumption of one peptide per spectrum. This approach merges peptide feature detection, de novo sequencing, and database search to maximize identification sensitivity and accuracy. In this video, we’ll go over the new features which include:

• MS1 feature-based peptide identification
• Support DIA data with database search (no library required)
• Improved identification of endogenous peptides
• Support ion-mobility LC-Ms
