Significant motifs returned by two-phase algorithm. For each simulation in Figure 2, we applied the two-phase algorithm to determine a set of significant motifs. The x-axis corresponds to the coverage after downsampling and the y-axis to the number of detected motifs. True positives counts (red) correspond to detection of motifs as described in Table 1. The total (and consensus) motifs for each are: 3 (3) for E. coli, 3 (3) for G. metallireducens, 4 (1) for C. salexigens, 3 (3) for B. cereus, 7 (3) for C. jejuni 81-176, 8 (2) for C.jejuni NCTC 11168). Parent false positives counts (green) are the parents of true motifs all other false positives are denoted by blue. Each row of subplots corresponds to a specific bacteria. Each column of subplots corresponds to the simulated WGA noise fraction. Error bars correspond to upper and lower quartiles.
