QUAST is a convenient tool for assembly evaluation. QUAST paper has been accepted to Bioinformatics, and now it is available in Advanced Access.
QUAST computes a number of well-known metrics, including contig accuracy, number of genes discovered, N50, and others. It also introduces some new statistics, like NA50 (see paper). An analysis results in summary tables available in various formats, including human-readable plain text, easy for parsing tab-separated tables, and LaTeX. Additionally, the tool generates colorful plots. All tables and plots are summarized in an interactive HTML report.
QUAST provides an intuitive command-line interface, and a detailed manual that guides though all the metrics. The sourсe code is available on sourceforge. Furthermore, we started a beta version of QUAST web interface. We appreciate your feedback regarding the tool and the website, firstname.lastname@example.org.
