Genome assembly evaluation tool.

QUAST evaluates genome assemblies by computing various metrics.
It works both with and without reference genomes.
The tool accepts multiple assemblies, thus is suitable for comparison.

QUAST releases are distributed on SourceForge. The source code and issue tracker are available at GitHub. We have recently started posting news and QUAST-related stuff on Twitter, follow us!

Download the latest version, see changelog and manual for details.
