From: Relating gene expression data on two-component systems to functional annotations in Escherichia coli
Sample expression profiles for two subsets of data. The top panels show gene expression profiles over multiple related experiments. The same set of curves are shown in the left and in the right panel. In each panel, a different subset of profiles is highlighted, corresponding to genes of a different functional designation. The bottom panels quantify the presence of patterns by identifying neighboring relationships among profiles using a product similarity measure. The number of neighbors, for all genes that show the function, is summarized in a histogram.
