How Ncbi Blastn Gets The List Of Organisms Programatically

Hi, Those who use the NCBI BLAST web site recognize the "Choose Search Set" box. After you select OTHER database and you type - in the Organism edit field - an organism name, similar organism names are listed (autocomplete feature). For example type "Bos t"

http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastn&BLAST_PROGRAMS=megaBlast&PAGE_TYPE=BlastSearch&SHOW_DEFAULTS=on&LINK_LOC=blasthome

Does somebody know which (Entrez?) database are queried and/or parameters used to list the autocompleted names? Sample code maybe?

Cheers

-1 for the unclear title. please edit the title of your question. Ideally, the title of a question should be such that any other user will be able to choose whether he/she is interested on the topic without having to open the discussion. For example, your question seems to be related to blast: you should say so in the title.

The database is the NCBI Taxononmy database . It is available at http://www.ncbi.nlm.nih.gov/Taxonomy/taxonomyhome.html . It can be searched as a web service using the NCBI-EUtilities (see the parameters here) or you can download it from here.

Check this url

http://blast.ncbi.nlm.nih.gov/corecgi/ajax/ajax.fcgi?dict=taxids_sg&q=mouse&$svc$=ac

Where:

  • dict=taxids_sg - taxids_sg dictionary
  • q - your query
  • $svc$=ac - autocomplete service

But I didn't find any public documentation about this service.
