Validation of Gene Predictions Figure 3. a. Histogram of distribution of pairwise sequence coverages within gene prediction clusters. Different curves refer to different sequence identity thresholds used for clustering. Color purple, red, brown, dark purple, pink, blue, cyan corresponds to cutoff values of 100%, 95%, 90%, 85%, 80%, 75%, 70%, respectively. b.
