Description

This is an Anvi’o database that stores information about your genomes, primarily for use in pangenomic analyses.

You can think of it like this: in a way, a genomes-storage-db is to the the pangenomic workflow what a contigs-db is to the the metagenomic workflow. They both describe key information unique to your particular dataset and are required to run the vast majority of programs.

What kind of information?

A genomes storage database contains information about the genomes that you inputted to create it, as well as the genes within them.

Specifically, there are three tables stored in a genomes storage database:

• A table describing the information about each of your genomes, such as their name, type (internal or external), GC content, number of contigs, completition, redunduncy, number of genes, etc.
• A table describing the genes within your genomes. For each gene, this includes its gene caller id, associated genome and position, sequence, length, and whether or not it is partial.
• A table describing the functions of your genes, including their sources and e-values.

Cool. How do I make one?

You can generate one of these from an internal-genomes (genomes described in bins), external-genomes (genomes described in contigs-dbs), or both using the program anvi-gen-genomes-storage.

Cool cool. What can I do with one?

With one of these, you can run anvi-pan-genome to get a pan-db. If a genomes storage database is the contigs-db of pangenomics, then a pan-db is the profile-db. It contains lots of information that is vital for analysis, and most programs will require both the pan-db and its genomes storage database as an input.
