Regulator on regulator visualization. The command-line module InteractionGraph.jar has the capacity to convert to visualization-ready file formats that can be read by Cytoscape for visualization . The functional transcriptional regulatory network dataset was filtered to show regulatory interactions only among transcription factors . Red connections indicate activation while green are indicative of repression. The arrowhead points from the regulator to the target that is being regulated.
