Figure 3From: Calculation of partial isotope incorporation into peptides measured by mass spectrometryA scatter plot of temporally transposed masses from 90,637 peptides ( m/z ) and decimal residuals of a Mycobacterium tuberculosis dataset (details see text)). Grey dots indicate cluster affiliation after classification by k-means clustering for (A) Unlabeled sequences (0 atomic %13C incorporation), (B) fully labeled (100 atomic %13C incorporation).Back to article page
