This is a file containing the taxonomy information for the genes in your contigs-db.

You can use anvi-import-taxonomy-for-genes to integrate this information into your contigs database. See this blog post for a comprehensive tutorial.

In its simplest form, this file is a tab-delimited text file that lists gene caller IDs and their associated taxonomy information. However, anvi’o can also parse outputs from taxonomy-based software like Kaiju or Centrifuge.

For example:

gene_caller_id  t_domain     t_phylum       t_class      ...
      1         Eukarya      Chordata       Mammalia
      2         Prokarya     Bacteroidetes  Bacteroidia
