Figure 4:

Usefulness assessment based on NG50 scaffold length and fraction of estimated genome sizes represented by gene-sized scaffolds of four cnidarian genome assemblies. NG50 scaffold length (primary y axis) is a metric for assessing the contiguity of assemblies, without disregarding differences in the estimated sizes of the genomes. The percentage of the estimated genome size that corresponds to gene-sized scaffolds, according to the average length in invertebrates (≥7 kb) and vertebrates (≥25 kb), are proxies for the usefulness of the assembled sequences (secondary y axis).
