eggnog‐hmmer‐search

Find homolog sequences in contigs or MAGs against a HMMER reference database.

For the full description of the action's inputs, outputs and parameters run qiime moshpit eggnog‐hmmer‐search --help in the terminal.

Inputs

• sequences (SampleData[Contigs] | FeatureData[MAG]): MAGs or contigs to search for homolog sequences against a Diamond database.
• idmap (EggnogHmmerIdmap % Properties('eggnog')): List of protein families in hmm-db.
• pressed-hmm-db (ProfileHMM[PressedProtein] % Properties('eggnog')): Collection of Profile HMMs in binary format and indexed.
• fastas (GenomeData[Proteins] % Properties('eggnog')): Seed alignments for the protein families in hmm-db.

Outputs

• eggnog-hits (SampleData[BLAST6]): Predicted hits. For each FASTA file in the input, a table is generated where every row is a hit (a predicted homolog) and columns are information about that specific hit/alignment. These tables or table, depending on whether there are multiple fasta files in the input, are all contained in this output artifact. For more information about these tables take a look at the Diamond documentation.
• table (FeatureTable[Frequency]): Feature table with counts of orthologs per sample/MAG.
