A heatmap of REDfly CRMs annotated with the catalog of putative enhancers provided in CBS. At the top are the chromatin signatures of REDfly entries  that can be associated with CBS H3K4Me1 enhancers, active enhancers, and poised enhancers, respectively. At the bottom, a magnification of the active enhancer map is shown to illustrate the distinct patterns of developmental stages for a fraction of these CRMs. The darker the intensity of the red color, the higher the number of putative enhancers overlapping a particular CRM. Please note that CBS does not directly produce this type of representation.
