Downloading hits from the MacVector 15.5 BLAST Map results tab

The MacVector 15.5 BLAST Map results tab is a unique interface for examining the annotations around hits to a query sequence. Each pane in the display represents a High Scoring Segment Pair, as seen in the BLAST Aligned Sequence tab. At the lower left corner of each pane is a Download button – when you click on it, a popup menu appears with several options.

The major options are to either download the entire genome, remembering this might be many Mbp in size, or to just download the displayed fragment. In general, MacVector displays the High Scoring Segment Pair region of the sequence, plus 2kb on either side to provide context, and that is what will be downloaded. To reduce the number of mouse-clicks when scrolling through a lot of results, Download to Last Folder places the downloaded sequence in the last folder that you selected (or your Downloads folder if you’ve never selected one before).
