architeuthis is named after Architeuthis dux, the giant squid. It also sounds like "archi-do-this", so giving instructions to your pet kraken.
architeuthis is a fast standalone command to supplement the Kraken suite of software tools such like Kraken2, KrakenUniq, and Bracken. I saw myself repeatedly rewriting the same code in my pipelines when dealing with Kraken output, like merging files or maninpulating lineage annotations. It also adds some functionality to dive deeper into the individual k-mer classifications for reads.
Main functionality
- Merge or combine outputs from Kraken/Bracken across many samples efficiently
- Add complete taxonomic lineage annotation to Bracken outputs
- Analyze mapping across taxa, e.g.
- How often did reads that matched one taxon also match another?
- Are there cross-domain matches in my data set?
- Filter Kraken mappings by several metrics
- mapping consistency
- multiple mappings on the final taxonomic rank
- mapping entropy on the final taxonomic rank
