Figure 4From: StralSV: assessment of sequence variability within similar 3D structures and application to polio RNA-dependent RNA polymeraseAmino-acid variability (y-axis) versus number of positional hits (x-axis) for three window sizes. Red circles: window size 70; blue diamonds: 80; green triangles: 90. Inset: positional hits at which the dominant residue occurs at frequency > = 80%. Circles: positional hit, variability coordinate pairs corresponding to the 11 positions shown in Fig. 5.Back to article page
