Comparing the distribution of returned top ranking fixed position motifs to the uniform distribution for the 4 tested significance scoring methods. (a) Scatterplot of the root mean square error (RMSE) for the distribution of returned top ranking motifs for each dataset size and motif length (nine combinations in total) from the uniform distribution versus the p-value of a Mann-Whitney test for rejection of the hypothesis that the distribution of top ranking motifs significance values were sampled from the uniform distribution. The top boxplot describes the p-value of a Mann-Whitney test and the boxplot on the right describes the RMSE data. (b) Comparison of 4 tested significance scoring methods for probability of being sampled from the uniform distribution. The heatmap plots, for each dataset size (horizontal axis) and motif length (vertical axis), the p-value of a Mann-Whitney test for rejection of the hypothesis that the distribution of top ranking motifs significance values was sampled from the uniform distribution.
