Peak Intensities. A) Histogram of intensities: X-axes – Intensity of log transformed root-means-square scaled peak intensities. Y-axis – Frequency. In grey: Histogram of the peak intensities that do not match a peak in any other peak-lists (peak-lists) within the same cluster (this mass is observed only once in the cluster). In magenta: Histogram of intensities of peaks that do match a peak within any peak-list within cluster (this mass is observed at least twice in the cluster). B) Altman Bland plot of intensities of the matching peaks for peak-lists pairs from within a cluster. C) Altman Bland plot of intensities of matching peaks for peak-lists pairs of between clusters.
