Nextclade: clade assignment, mutation calling and quality control for viral genomes

🤖 Plain-English Summary

The variants of concern (VoCs) of SARS-CoV-2 have highlighted the need for a global molecular surveillance of pathogens via whole genome sequencing. Nextclade aligns viral genomes to a reference sequence, calculates several quality control (QC) metrics, assigns sequences to a clade or variant, and identifies changes in the viral proteins relative to the reference sequence.

🔑 Key Findings

• Such sequencing, for SARS-CoV-2 and other pathogens, is performed by an ever increasing number of labs across the globe, resulting in an increased need for an easy, fast, and decentralized analysis of initial data.
• Nextclade aligns viral genomes to a reference sequence, calculates several quality control (QC) metrics, assigns sequences to a clade or variant, and identifies changes in the viral proteins relative to the reference sequence.
• Nextclade is available as a command-line tool and as a web application with completely client based processing, meaning that sequence data doesn't leave the user's browser.
