Pearson correlation coefficients (bars) and their p -values (dashed lines) for divergence (black) and diversity level (red) of neighboring windows of size 100 kb. The x-axis gives the number of the neighboring windows, starting from 1, i.e. nearest neighbor, up to 50, i.e. windows separated by 49 windows. The y-axis indicates the correlation coefficient on the left side and the related p-value (log-scale) on the right.
