Root recovery of Rootine v.2 for the worse and best case scenario. a, c Comparison with the former Rootine v.1 and the RLD determined with destructive sampling and scanning of washed-off roots (WinRHIZO) for the worse case and the best case scenario, respectively. The dashed line indicates the 1:1 line. b, d Visual comparison of the segmented root systems obtained with Rootine v.1 and Rootine v.2 for the corresponding sample circled in black on a and c for the worse case and the best case scenario, respectively. Roots detected by both algorithms are depicted in black, the ones only detected by Rootine v.2 are shown in blue, whereas roots only detected by Rootine v.1 are shown in red
