Zhang, W. & Sun, W. Feature-based Peptide Identifications with PEAKS Studio X. (Application Note). 1/11/2018.
PEAKS Studio X introduces a feature-based identification method into its unique de novo assisted identification workflow, which significantly maximizes the efficiency of peptide identification for shotgun analysis of complex proteomes. The deconvolution of chimeric MS2 generated from cofragmented peptides enables 1.11 identified peptides per tandem spectrum, resulting in an increase of 40% more peptides and 24% more proteins identified than PEAKS Studio 8.5.
