Run dbCAN CAZymes on contigs-db.
🔙 To the main page of anvi’o programs and artifacts.
This program annotates genes in your contigs-db with functions using dbCAN CAZyme HMMs
Before you run this program, you’ll have to set up the CAZyme database on your computer with the program anvi-setup-cazymes.
The CAZyme database is based on protein sequences, so anvi’o will convert your genetic information into protein sequences and then use HMMs to compare them to the database.

To run, you’ll need to provide a contigs-db and the output will be a functions artifact. Here is a default run:
anvi-run-cazymes -c contigs-db
If you stored the cazyme-data that you got from running anvi-setup-cazymes in a custom location, you’ll need to provide that path as well.
anvi-run-cazymes -c contigs-db \ --cazyme-data-dir cazyme-data
By default, this uses
hmmsearch to run HMMs. You can choose to use
hmmscan instead by running
anvi-run-cazymes -c contigs-db \ --cazyme-data-dir cazyme-data \ --hmmer-program hmmscan
Use the parameter
--noise-cutoff-terms to filter out hits. The default value is
--noise-cutoff-terms -E 1e-12. If you want to explore filtering options, check out the help menu of the underlying hmm program you are using e.g.
anvi-run-cazymes -c contigs-db \ --noise-cutoff-terms “-E 1e-14”
