Sorting. The top two track groups show subspecific origin and haplotype similarities with strains shown in the default order. The lower two tracks show these tracks after automatic sorting according to the haplotype similarity at the selected cursor position. Strains are sorted by haplotype at the selected position. Strains with the same haplotype are further sorted by adjacent positions until all strains are distinct. The subspecific origin tracks are automatically ordered to match the sorted order as determined by the haplotype color.
