Two-dimensional projection plots for consistent taxonomy objects. Different colors correspond to X-type assignments in method A (green; consistent objects in method A1 and A2), comparative taxonomy types in method B (blue), consistent objects between method A and B assignments (red), and all our samples (black). D- and L-type objects in method B correspond to a large portion of objects with X type in the method A result, whereas K and X types in method B do not correspond to X type in method A.
