I have done a blastx and use the outfmt 6 option, because I want to work in the tables format. When I do this I get subject ids of the type


et cetera.

However, in this blastx output format I cannot find any option that will give me the descriptions of these blast hits. Could anyone advice me how I can link these subject ids with descriptions of the sequences, e.g., 'amino acid transporter ANTL1-like'? I'd be much obliged.


  • $\begingroup$ Does the fasta/gb file from which this BLAST database was built have these descriptions in the header? If not take a look here: biostars.org/p/110000 $\endgroup$ – mimat Mar 16 '17 at 14:52
  • $\begingroup$ You have to map these ids to a file that contains gene description. Usually the GTF/GFF file for that reference genome would have these descriptions. $\endgroup$ – WYSIWYG Mar 17 '17 at 6:59
