As you may have read in previous posts, NCBI is phasing out sequence GIs and transitioning to accession.version identifiers. To help you prepare for this transition, we created sample BLAST databases that will help you make code changes to your programs and workflows for the switch to accession identifiers.
The sample databases, env_nr_v5 and tsa_nr_v5, are on FTP.
