Relative N50 size. Cumulative histogram plotting the relative N50 size (x-axis; see text for definition) against the percentage of chromosomes (y-axis) for which the contigs achieve an N50 size at least that large. For example, approximately 40% of chromosomes yield a relative N50 contig size of at least 50% of the genome length when using 500-nt reads.
