"Here, the contig and scaffold N50 of the YH genome were ~20.9 kbp and ~22 Mbp"
N50 statistic computed for the contigs produced by the assembly process. A contig N50 is calculated by first ordering every contig by length from longest to shortest. Next, starting from the longest contig, the lengths of each contig are summed, until this running sum equals one-half of the total length of all contigs in the assembly. The contig N50 of the assembly is the length of the shortest contig in this list.
