Figure 9From: Proteomics, lipidomics, metabolomics: a mass spectrometry tutorial from a computer scientist's point of viewDifference detection. Comparative or differential MS-omics aims to identify possible differences between two sets of replicate studies. In this case the three red signals are cases--samples from individuals of interest--and the blue signals are controls--samples from baseline individuals. The center peak clearly indicates a differentially expressed analyte.Back to article page
