Importance of each feature. The importance of each attribute as estimated by information gain is shown for the YGOB ortholog set. At left, the divergence related scores are shown by light blue color lines. For local divergence features LD(i), only the residue number i is listed. Dark blue colored lines denote standard features of the N-terminal 40 residues such as physico-chemical properties or amino acid composition. The suffix “f” denotes amino acid composition from the full length of the protein.
