A pipeline for mapping, calling, and annotation of SARS-CoV2 variants.

A workflow for mapping and consensus generation of SARS-CoV2 whole genome amplicon nanopore data implemented in the Nextflow framework. Reads are mapped to a reference genome using Minimap2 after trimming the amplicon primers with a fixed length at both ends of the amplicons using Cutadapt. The consensus is called using Pysam based on a majority read support threshold per position of the Minimap2 alignment and positions with less than 30x coverage are masked using ‘N’.

This is the official repository of the SARS-CoV-2 variant surveillance pipeline developed by Danish Technical University (DTU), Eotvos Lorand University (ELTE), EMBL-EBI, Erasmus Medical Center (EMC) under the Versatile Emerging infectious disease Observatory (VEO) project. The project consists of 20 European partners. It is funded by the European Commission.
