Outputs of the selected piecewise linear model in the case of a lateral root (rum-1 A′40) for which the optimal 3-segment piecewise linear function does not fit biological assumptions (piecewise linear function not approximately continuous). (A) Optimal 3-segment piecewise linear function, sub-optimal 3-segment piecewise linear function corresponding to the 3rd segmentation and first root hair position; (B) Posterior division zone (DZ), elongation zone (EZ), and mature zone (MZ) probabilities; The uncertainty intervals for the DZ-EZ and EZ-MZ limits are in gray. (C) Posterior segmentation probabilities highlighting the difference between the 3rd segmentation and the optimal segmentation.
