This is the Linnaeus Viewer. Once it has retrieved your results from the server, you will see nested boxes containing trees. Left click zooms in. Right click (ctrl-click on Mac) zooms out. Alt-left button drag scrolls the view. Click on a taxonomic group name or an individual sequence name to view an alignment.
Move the slider at the top to gray out sequences that are more than the given e-value (or percentage identical) away from your BLAST query sequence.
