Figure 3. Ring-like topology of HSat2,3 subfamily projections reflects tandem repeat unit organization.

Feature vectors representing simulated reads from a 1.77 kb clone sequence from the HSat2 array on chromosome 1 are colored by their starting position on the clone sequence and overlaid on a PCA projection of HSat2A2 reads (black). Arrows below this plot illustrate the tandem nature of the 1.77 kb repeat, which yields the observed ring-like projection as reads are sampled from different subregions of the tandem repeat unit.
