Sliding-window analysis of F ST at SNPs among viral samples. A. DWV values of FST. B. IAPV values of FST. Values were calculated with popoolation2 [28] using a window size of 100 bases and a step size of 25 bases. A minimum read count of 4 per site at a minimum of 40% of sites was required within each window or else no estimate was calculated (shown as gaps in the continuity of the line).
