\label{fig:HIVHt} Summary statistics at each genome genomic  position for HIV-1. The small green circles and blue pluses are the $Ht(D_i)$ values and $Ht(N_i)$ values, respectively. For genome site $i$ that belongs to the signal set, its $Ht(D_i)$ value is highlighted in a large red circle. The dotted line ($d_0 = 4.452$) is the threshold obtained from our method (see Figure \ref{fig:HIVCt}). The seven red circles above the threshold are the substitution sites: 48, 55, 243, 245, 250, 264, 268. The six blue plus signs above threshold are 70, 72, 168, 219, 268, and 289. Site 268 is excluded from the noise site list since $Ht(D_{268})>Ht(N_{268}) $.
