8.19 Use links and topcomboN to Make Sense of Alignment Groups

WU-BLAST has two very useful parameters for displaying alignment groupings. topcomboN sorts alignments into groups and labels them. The links parameter shows the order of alignments in a group, which is much like the order of a gene's exons. Figure 8-9 displays these features.
