A set of non-covalent contacts (within 13Angstroem of Calpha) visualised in a translation/rotation invariant framework.
Some clear clusters of preferred orientations are visible. 4 dense clsuters stem from heleical conatcs of subsequent turns. The ring along the x-axis corresponds to a 3D version of the classical ramachandran plot. 2D Maps can be extracted by spherical projection, indicated by the transparent sphere.
