NCBI's Influenza Virus Database Programmatic/ API Access

I would like to retrieve nucleotide FASTA and meta files from NCBI's Influenza Virus Database programmatically/ API.

I've tried using e-utility, but the Influenza Virus Database is not an option as a search criteria - I am wondering if there's anyone who worked out the criteria (the stuff after the base URL, e.g.: database, words etc.) using e-utility to get results out of the Influenza Virus Database.

If that is possible, would appreciate the info on how to filter out the country/region too with the e-utility URL.

I've also looked at the FTP option on their website, however, the FTP has not been updated since ~Oct 2020 for some reasons...? :(

Thank you for any advise and help in advance!

Good morning,

You can access virus metadata and data through the web using the NCBI Virus page or programmatically using NCBI Datasets. The. NCBI virus data package includes the genomic FASTA sequences plus metadata in JSON-Lines format. To download the data package, you run the following commands. I'm including one for each type of Influenza, but NCBI Virus has some more specific classifications, such as Influenza A Virus (A/equine/Newmarket/1/1993(H3N8)).

datasets download virus genome taxon 197911 --filename alphainfluenza.zip
datasets download virus genome taxon 197912 --filename betainfluenza.zip
datasets download virus genome taxon 197913 --filename gammainfluenza.zip
datasets download virus genome taxon 1511083 --filename deltainfluenza.zip

If you want to filter the assemblies by country, you can use the --geo-location flag and the country of interest. For example:

datasets download virus genome taxon 1511083 --filename deltainfluenza_USA.zip --geo-location USA

When you unzip those files, you should find all the genomes in the file genomic.fna and all the metadata in the data_report.jsonl. NCBI datasets has a companion tool called dataformat that can convert JSON-Lines to tsv. You can read more about the virus-genome fields in this page.

Archive:  deltainfluenza.zip

  inflating: delta/ncbi_dataset/data/genomic.fna  
  inflating: delta/ncbi_dataset/data/virus_dataset.md  
  inflating: delta/ncbi_dataset/data/dataset_catalog.json

Please let me know if you run into any issues. I hope this helps!

Viral genome sequences are available via FTP here (updated last week): https://ftp.ncbi.nih.gov/genomes/Viruses/AllNucleotide/

In associated metadata file : https://ftp.ncbi.nih.gov/genomes/Viruses/AllNuclMetadata/AllNuclMetadata.csv.gz I see plenty of Influenza entries
