ePK features. a Features measured for classification. For each aligned residue, we calculate the φ, ψ and χ1 angles, depicted for residue 138 (top). In addition, for quads of adjacent residues, we calculate the pseudo-dihedral through their Cα atoms, with Pd_137-140 shown (bot). b Selected features on template structure colored by importance from white (no weight) to red (high weight)
