7. Descriptions Tab

This default tab shows a list of description rows for the sequences matched in the database. Click a description to go to the alignment. To the right of the descriptions are columns for the organism (scientific name) and BLAST statistics for the match. A smaller E value (expected value) represents a closer or more “significant” match. For more information on BLAST E values, see BLAST Results: Expect Values, Part 1 and Part 2. The Accession column links to the specific record(s) in the NCBI sequence databases (nucleotide or protein). These columns are customizable via the “Select columns” pull-down option.
