The trajectories of the set size of $S_1^d, S_2^d, S_3^d$ with the threshold shown as a doted dash  line ($d_0 = 4.452$) for the human immunodeficiency virus 1. The right panel is a zoom-in view of the left. At threshold $d_0 = 4.452$, seven locations are identified as substitution sites due to the treatment and five locations are identified as high genetic variability sites not due to the treatment.
