In this example the first helical curve H14 is computed using the first quadruple of backbone atoms {a1,a2,a3,a4}, the second curve H25 the next quadruple of atoms {a2,a3,a4,a5} and so on. For a pair of two consecutive interior atoms up to three slightly different curves could be computed. The final model curve for the segment between a pair of consecutive atoms is their average (Eq 3).
