Neighbor-joining tree for Dali(S12). A) The complete cluster tree for distances from the 12D SMACOF MPSS based on Dali. Colors indicate membership in the 200 most populated SCOP Superfamilies. Because it is difficult to distinguish highly similar colors, a smaller number of distinct colors are reused periodically across the tree, while guaranteeing that color labels are locally unique. The reader may note that different superfamilies are found at different depths within the tree, so that the use of a single threshold for all clusters is only approximate. B) The part of the tree that corresponds to the PH domain-like superfamily. This superfamily is entirely and exclusively contained within a single subtree. C) The region of the tree containing the Immunoglobin and Fibronectin Type III superfamilies. These superfamilies do not correspond either to a single subtree or to a single depth within the tree.
