Summary statistics for assemblies of Mock A

	Genome fraction (%)	Genomes covered > 50%	Contigs	Misassemblies	Mismatch rate	Indel rate
MEGAHIT	98.233	11/12	1902	3	75.7	3.33
MetaCortex	99.886	12/12	339	0	4.43	3.44

Note: The contigs field describes the number of contigs in the assembly of length greater than or equal to 500 bp. Misassemblies are defined in the text above and include chimeric assemblies. Mismatch and indel rates are the number of occurrences per 100 kb. The NGA50 for each genome in the sample can be found in Figure 1B.
