Can consume

Can provide

codon-frequencies-txt aa-frequencies-txt

Usage

This program calculates the frequency of each codon or amino acid of every gene in your contigs-db.

To run with all standard parameters, simply provide a contigs-db and path for the output file as follows:

anvi-get-codon-frequencies -c contigs-db \ -o name/of/output_file.txt

The output of this is a codon-frequencies-txt that counts the number of times each codon appears in all of your genes.

If instead you want to calculate the data for the amino acids, run

anvi-get-codon-frequencies -c contigs-db \ -o name/of/output_file.txt \ --return-AA-frequencies-instead \ --gene-caller-id MY_FAVORITE_GENE

In this example, the flag gene-caller-id means that it will only count the amino acid frequencies of a single gene, namely MY_FAVORITE_GENE.

You can also return the data as a percent of the total number of codons or amino acids in the gene (with the flag --percent-normalize) or calculate the percent that each codon encoding the same amino acid appears in the gene (for example, 0.4 GCT and 0.6 GCC for alanine) (with the flag --merens-codon-normalization).
