RefSeqFE feature distributions. (A) Categorized feature counts from human AR 109.20201120 on the GRCh38.p13 genome assembly with grouping by feature class. The pale blue labels indicate the feature counts per category; categories and a full breakdown of feature types and counts are available in Supplemental Table S2A. (B) Box plot showing feature length distributions for all human features (light gray) and individual feature classes, with coloring as in A. Some outliers (maximum length 141,940) are not displayed because the y-axis was scaled to better visualize the distributions of shorter features. Length distributions per feature type are provided in Supplemental Figure S3 with customized scaling for each class: n = 9862, 1357, 1379, 926, and 6200 sample points. Additional statistics including minimums, maximums, averages, and standard deviations from the mean are provided in Supplemental Table S2A. (C) Categorized feature counts from mouse AR 109 on the GRCm39 genome assembly as shown for human in A. (D) Box plot showing feature length distributions for all mouse features (light gray) and individual feature classes, as described for human in B: n = 2271, 109, 690, and 1472 sample points. Additional details are provided in Supplemental Figure S4 and Supplemental Table S2A. (E) Summary table with overall counts of annotated features, biological region loci, and genome coverage for the indicated AR.
