Assembling SARS-CoV-2 Genomes

A workflow for assembly of SARS-CoV-2 sequences from Illumina data, including quality trimming and removal of amplicon primers, map to reference, SNP calling and consensus generation.

Betacoronavirus BLAST

NCBI has a new BLAST database for betacoronaviruses. To add this database to the Geneious NCBI BLAST, go to Tools -> Add/Remove Databases ->Set up BLAST Services. Under the NCBI tab, click Edit Databases, and then Add+. Enter the details as in the screenshot – ensure the database name is written exactly as shown here.

To update this list with new sequences as they are released, we recommend setting up an Agent.  To do this, go to View -> Agents, then click Create.  Select Nucleotide under Search Database, and search by Organism contains “Severe acute respiratory syndrome coronavirus 2”, as shown in the screenshot below.

Note that there is a delay of a few days between a sequence appearing on the NCBI SARS-CoV-2 data hub and being available for searching in NCBI Nucleotide.
