Possible residue shifts for an aligned pair of SSEs from two different protein structures. Two proteins (white: source protein, gray: target protein) consisting of three SSEs each. Each bold dot within a SSE represents a residue. Lines connect residue pairs of different SSEs that are in contact. Solid lines refer to contacts in the source protein; dotted lines refer to contacts in the target protein. For conserved contacts, residue pairs are connected by horizontal solid and dotted lines, simultaneously. Part a: No contacts of source and target proteins are conserved (${\text{q}}_{\text{res}}^{\text{st}}$ = 0). Part b: A maximum of five contacts from a total number of seven contacts are conserved (${\text{q}}_{\text{res}}^{\text{st}}$ = 5/7).
