Organism & Taxonomy
SeqDesk integrates with the NCBI taxonomy database to identify organisms for each sample. Correct taxonomy assignment is required for ENA submission.
Taxonomy Lookup
The Organism field in the sample table provides an autocomplete search:
- Start typing a scientific name, common name, or partial match
- Results appear from the local taxonomy database (~6,000+ entries)
- Select the correct organism
- Both

Common Identifiers
Species-Level Samples
For samples from a known species, search by scientific name:
| Search | Tax ID | Scientific Name |
|---|---|---|
| E. coli | 562 | Escherichia coli |
| human | 9606 | Homo sapiens |
| mouse | 10090 | Mus musculus |
Metagenome Samples
For metagenomic samples, use the appropriate metagenome identifier:
| Environment | Tax ID | Scientific Name |
|---|---|---|
| Human gut | 408170 | human gut metagenome |
| Soil | 410658 | soil metagenome |
| Marine | 408172 | marine metagenome |
| Freshwater | 449393 | freshwater metagenome |
| Wastewater | 48479 | wastewater metagenome |
These metagenome IDs are required by ENA for environmental samples where a single species cannot be assigned.
Tax ID Requirements
The taxId field is critical for:
- ENA submission — every sample must have a valid NCBI taxonomy ID
- MIxS compliance — the taxonomy determines applicable metadata standards
- Pipeline configuration — some pipelines use taxonomy for reference database selection
If you cannot find your organism in the autocomplete, verify the name at NCBI Taxonomy and ensure the taxId is correct.
Updating Taxonomy
Taxonomy can be updated:
- During order creation in the sample table
- On the order detail page (while in DRAFT status)
- In the study sample table when editing MIxS metadata
