Rockhopper’s operon predictions are compared against external operon databases based on operons with experimental evidence. The first column indicates the genome. The second column indicates the external database that Rockhopper’s predictions are compared against. The third column indicates the sensitivity of DOOR’s operon predictions. The fourth column indicates the specificity of DOOR’s operon predictions. The fifth column indicates the sensitivity of Rockhopper’s operon predictions. The sixth column indicates the specificity of Rockhopper’s operon predictions.
