QUAST: Quality Assessment Tool for Genome Assemblies


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.
