BLAST Databases: Which One to Search?

What type of data do you want to search against? For example:

  • characterized sequences?
  • specialized sequences (e.g., ESTs, STSs, HTGs)?
  • complete genomes or chromosomes?
(Note: The two documents above are maintained separately and might not be in complete synch with each other if new BLAST databases were recently made available. Therefore, if you don't see your database of interest described on one document, check the other one as well. Please notify blast-help@ncbi.nlm.nih.gov of any discrepancies and they will make the fix.)
