**What it does**

Reports standard measures of *de novo* assembly quality such as number of contigs, sum of contigs, mean contig length, and N50.

**Parameter list**

Minimum length
Only include contigs of this size or greater for calculating statistics.

**Output**

Num contigs
Total number of contigs in the assembly

Sum of contig lengths
Total sum of contig lengths

Maximum contig length
Maximum of the contig lengths

Mean contig length
Average contig length

N50
Contig length at which 50% of the assembly is contained in contigs of this size or greater.

99%
Number of contigs accounting for 99% of the observed assembly.
