Table 3. Comparison of P. Stipitis assembly contig characteristics (including contigs of at least 100 bp).

Assembler	No. Contigs	Total Size (Mbp)	Contig N50 (no. / kbp)	Contig error rate	Reference coverage	Unique coverage
ABySS	132	15.48	21 / 263	1/29 kbp	97.8%	92.2%
Meraculous	489	14.70	44 / 101	<1/15000 kbp	95.8%	95.8%
SOAPdenovo	561	14.58	64 / 65	1/6.4 kbp	95.2%	95.1%
Velvet	572	14.69	87 / 53	1/15 kbp	96.5%	95.4%

Contig error rate is measured for only the single best-aligning BLAST HSP per contig. Reference coverage is based on the total number of bases spanned by at least one HSP; unique coverage is based on the total number of reference bases spanned by exactly one HSP.
