Figure 5. Performance of different motif tools on target sets of long motifs.

(a) Summary of the numbers of target sets with different motif lengths. The 213 target sets of long motifs were divided into 9 groups according to the corresponding motif lengths. The number of target sets in each group is listed. (b) Performance of the nine motif tools on the target sets of long motifs at different lengths. Nine motif tools were applied to 9 groups of long motif target sets (as described in a). For each tool, prediction accuracy scores were averaged for target sets of the same group.
