anvi-run-ncbi-cogs [program]

This program runs NCBI's COGs to associate genes in an anvi'o contigs database with functions. COGs database was been designed as an attempt to classify proteins from completely sequenced genomes on the basis of the orthology concept..

Usage

This program associates genes in your contigs-db with functions using NCBI’s Clusters of Orthologus Groups (COGs) database.

Before you run this program, you’ll have to set up the COGs database on your computer with the program anvi-setup-ncbi-cogs.

As mentioned above, the COGs database is no longer actively added to, so you might also want to consider using a separate database. As of yet, anvi’o does not have a program to accesss the eggNOG database (but instructions to use this database to get and import function information are here), but does have the functionality to use the Pfams database (check out anvi-run-pfams for more information) and the KOfamKOALA database (see anvi-run-kegg-kofams).

To run, you’ll need to provide a contigs-db. If you stored the cogs-data that you got from running anvi-setup-ncbi-cogs in a custom location, you’ll need to provide that path as well. The output is a functions artifact.

Without the flag --cog-data-dir, anvi’o will just search in the default location.

By default, this program uses DIAMOND in the “fast” setting for database searching. To instead run in “sensitive” mode, just call:

You can also use blastp to search, by running:
