anvi-run-scg-taxonomy [program]

The purpose of this program is to affiliate single-copy core genes in an anvi'o contigs database with taxonomic names. A properly setup local SCG taxonomy database is required for this program to perform properly. After its successful run, anvi-estimate-scg-taxonomy will be useful to estimate taxonomy at genome-, collection-, or metagenome-level).

Usage

This program associates the single-copy core genes in your contigs-db with taxnomy information.

Once this information is stored in your contigs-db (in the form of a scgs-taxonomy artifact), you can run anvi-estimate-scg-taxonomy or use the anvi-interactive and enable “Realtime taxonomy estimate for bins.” Check out this tutorial for more information.

In order to run this program, you’ll need a scgs-taxonomy-db, which you can set up by running anvi-setup-scg-taxonomy.

What does this program do?

In short, this program searches all of the single-copy core genes that it uses for this workflow (which are the 22 listed on this page) against the GTDB databases that you downloaded, and stores hits in your contigs-db. In other words, it finds your single-copy core genes and assigns them taxonomy. This way, it can use these single-copy core genes later to estimate the taxnomy of larger groups of contigs that include these single-copy core genes when you run anvi-estimate-scg-taxonomy.

Sweet. How do I run it?

In case you’re running this on a genome and not getting any hits, you have the option to try lowering the percent identity required for a hit (as long as you’re careful with it). The default value is 90 percent.
