Figure 1.

Schematic illustration of the strategy used in the species identification by the insertions/deletions (SPInDel) method. (a) Illustration of the sequence alignment for three hypothetical species. Four conserved regions (green boxes) define three hypervariable domains (dotted brown lines). A section of the alignment is magnified to show the presence of multiple gaps in hypervariable regions. (b) Each species is identified by a numeric profile resulting from the combination of lengths in hypervariable regions.
