I want to get an evolutionary analysis by using NCBI NR database and Uniport database. But NR database has only blastdb and fasta format in which I can not find the taxon information. How can I get the NCBI NR database in genbank format.Thanks.
The accession2taxid folder provided the Accession number - taxonomy id relationships. You might also be interested in the gi_taxid_* files, which provide GI - taxonomy id relationship. But GenBank will not support GI soon.
