  1. This table illustrates all gene expression/regulation combinations for a transcription factor T (with relative expression level t), a target gene G (with relative expression level g), and a regulatory interaction of type r. For the first four rows, COMA would suggest that the gene regulation type r contradicts the given gene expression levels for the transcription factor T and the target gene G.
