^*Contigs of length <300 bp were not counted.

^†“Total” refers to the total number of bases in the contigs.

^‡“Max” and “Mean” refer to the length of the longest contig and the mean length of contigs, respectively.

^§N50 is the size of the smallest contig such that 50% of the assembled bases are in the contigs of size equal to or larger than the N50 value.

^¶A contig is misassembled if it cannot be aligned in full-length to the reference genome.

^||The proportion of the reference genome covered by the aligned contigs.
