Network of GEO differential expression profiles. (A) We calculated p-weighted correlations between 9,415 differential expression profiles from GEO and connected highly similar profiles (q < 0.001). Nodes are colored according to experimental variable (e.g., time). Dense clusters tend to represent multiple profiles from the same experiment. We identified multi-experiment clusters corresponding to processes including muscle injury, mammary gland development, and glioma grade. For a high resolution figure, see Additional files 3 and 4. (B) Close-up of a multi-experiment cluster. DE profile nodes are re-colored to correspond to the GEO DataSet from which they originate, and node shape represents experimental variables. *Compares gestation day 14 to gestation day 16.
