The correlation between the root-to-tip distances for the strains included in the study and the isolation time estimated using Path-O-Gen in the initial core alignment (a) and in the non-recombining core alignment (b). The two outlier points in b correspond to strains ID_3355 and ID_7371, which have probably acquired mutations at a slightly higher rate than the other strains present in the data set. Removing these two outliers, the correlation and R2 parameters do not change significantly.
