MetaQUAST evaluates and compares metagenome assemblies based on alignments to close references. It is based on QUAST genome quality assessment tool, but addresses features specific for metagenome datasets:

  • Huge species diversity – the tool accepts multiple references and makes multi-genome tables and plots, including Krona charts.
  • Commonly unknown species content – the tool automatically detects and downloads reference sequences from NCBI.
  • Presence of highly relative genomes – the tool detects chimeric contigs and reports “interspecies misassemblies” in addition to the regular assembly error types.

MetaQUAST can be fed with multiple assemblies, thus it is perfect for comparison.

MetaQUAST is distributed within the QUAST package since version 2.2: download the latest version, see the changelog.
