Organism: the genome being assembled. Assembled by: the short-read data used for correction and/or assembly. Number of contigs: the number of contigs comprising the assembly. N50: N such that 50% of the genome is contained in contigs of length ≥N. Number of structural differences: the sum of inversions, relocations, and translocations versus the reference using GAGE metrics [37]. Number of discordant bases: total number of different bases when compared to the reference. QV: estimated from the number of indels and SNPs as ${log}_{10}\left(\frac{\mathrm{assembly}\mathrm{length}}{\#\mathrm{incorrect}\mathrm{bases}}\right)*10$ . Indels >5 bp: the number of indels >5 bp reported by GAGE metrics [37]. Assemblies were generated as in Tables 2 and 3.
