Usage

This program can work with anvi’o contigs-db, external-genomes, or internal-genomes files to return sequences for HMM hits identified through the default anvi’o hmm-sources (such as the domain-specific single-copy core genes) or user-defined hmm-sources (such as HMMs for specific antibiotic resistance gene families or any other targets).

Using it with single-copy core genes in default anvi’o HMMs make it a very versatile tool for phylogenomics as the user can define specific sets of genes to be aligned and concatenated.

Learn available HMM sources

anvi-get-sequences-for-hmm-hits -c contigs-db \ --list-hmm-sources

AVAILABLE HMM SOURCES =============================================== * ‘Bacteria_71’ (type: singlecopy; num genes: 71) * ‘Archaea_76’ (type: singlecopy; num genes: 76) * ‘Protista_83’ (type: singlecopy; num genes: 83) * ‘Ribosomal_RNAs’ (type: Ribosomal_RNAs; num genes: 12)

Get all sequences in a given HMM source

anvi-get-sequences-for-hmm-hits -c contigs-db \ --hmm-source Bacteria_71 \ -o genes-fasta

Learn available genes in a given HMM source

Please note that the flag --list-available-gene-names will give you the list of genes in an HMM collection (for example, for Bacteria_71 in the following use case), and it will not give you the list of genes in your genomes or metagenomes that are matching to them. You can generate a table of HMMs across your genomes or metagenomes with another program, anvi-script-gen-hmm-hits-matrix-across-genomes.

Get sequences for some sequences in a given HMM source

anvi-get-sequences-for-hmm-hits -c contigs-db \ --hmm-source Bacteria_71 \ --gene-names Ribosomal_L27,Ribosomal_L28,Ribosomal_L3 \ -o genes-fasta

Get HMM hits in bins of a collection

anvi-get-sequences-for-hmm-hits -c contigs-db \ -p profile-db \ -C collection --hmm-source Bacteria_71 \ --gene-names Ribosomal_L27,Ribosomal_L28,Ribosomal_L3 \ -o genes-fasta

Get amino acid sequences for HMM hits

anvi-get-sequences-for-hmm-hits -c contigs-db \ -p profile-db \ -C collection --hmm-source Bacteria_71 \ --gene-names Ribosomal_L27,Ribosomal_L28,Ribosomal_L3 \ --get-aa-sequences \ -o genes-fasta

Get HMM hits independently aligned and concatenated

The resulting file can be used for phylogenomics analyses via anvi-gen-phylogenomic-tree or through more sophisticated tools for curating alignments and computing trees.

anvi-get-sequences-for-hmm-hits -c contigs-db \ -p profile-db \ -C collection --hmm-source Bacteria_71 \ --gene-names Ribosomal_L27,Ribosomal_L28,Ribosomal_L3 \ --get-aa-sequences \ --concatenate-genes \ --return-best-hit -o genes-fasta

Want to play?

You can play with this program using the anvi’o data pack for the infant gut data and by replacing the parameters above with appropriate ones in the following commands.

Download the latest version of the data from here:
