Table 1. Peptide details for testing performance of the peak detection with different quality of fragmentation in spectra.

Spectrum	Peptide	MWD		Distiller
		Score a)	No. ion b)	Score	No. ion
SpecH	YNGVFQECCQAEDK	75	52	115	39
SpecM	SLHTLFGDELCK	50	34	49	14
SpecL	DDPHACYSTVFDK	34	24	14	8

^a) “Score” is the MS/MS Mascot search score. ^b) “No. ion” is number of matched ions from the peak lists to the expected peptide fragment ions.
