Fetches the number of times each amino acid occurs from a contigs database in a given bin, set of contigs, or set of genes.

splits-txt contigs-db profile-db collection
Similarly to anvi-get-codon-frequencies, this program counts the number of times each amino acid occurs in a given sequence, whether that’s a collection, bin, set of contigs (listed in a splits-txt), or a set of genes. The output of this is a aa-frequencies-txt.
There are four possible things you can count the amino acid frequencies in:
Examples for each are below.
To count the amino acids in all of the contigs in a contigs-db, you can just provide the contigs-db of interest, as so:
anvi-get-aa-counts -c contigs-db \ -o path/to/aa-frequencies-txt
To count the amino acid frequencies for a series of bins, you’ll need to provide three additional parameters: the profile-db that you used for binning, the collection that your bins are contained in, and a text file that describes which bins you are interested in. This text file should have only one bin ID per line.
So, your run would look something like this:
anvi-get-aa-counts -c contigs-db \ -o path/to/aa-frequencies-txt \ -p profile-db \ -C collection \ -B my_favorite_bins.txt
my_favorite_bins.txt would look something like this:
Just provide a splits-txt file that lists the contigs you want to look at.
anvi-get-aa-counts -c contigs-db \ -o path/to/aa-frequencies-txt \ --contigs-of-interest splits-txt
Just provide a list of gene caller ids, straight into the terminal, like so:
anvi-get-aa-counts -c contigs-db \ -o path/to/aa-frequencies-txt \ --gene-caller-ids gene_1,gene_2,gene_3
