QUAST: Quality Assessment Tool for Genome Assemblies

Dear users! Our website moved to! New QUAST page is here.


QUAST evaluates genome assemblies. For metagenome assembly evaluation, see MetaQUAST project. For contig alignment visualization, see Icarus project.

QUAST works both with and without a reference genome.

The tool accepts multiple assemblies, thus is suitable for comparison.
