Welcome @Joel_Brown
Yes, you are correct! The taxonomy functions are not wrapped into the BLAST+ functions directly. Instead, you can cut out the hits and run one of these tools to pull in the extra data you are interested in, then join columns as wanted.
- Fetch taxonomic representation (find this at UseGalaxy.eu for now)
- NCBI Datasets Gene download gene sequences and metadata
Placing all steps into a simple workflow is what most do. Then, that workflow functions in practical use as a “single custom tool” when you execute it.
For how to do this exactly, I’m guessing you already know about the our tabular data parsing tools but in case not or for anyone else reading later on: please try a search in the tool panel with common utility names, or see our tutorial here for a short tour.
- GTN Materials Search (query=olympics)
Please give that a try and let us know if you have any follow up questions!
