Figure 8 (a) Bones skeletonization (Kleywegt, 1996) (cyan) shown within a contour from the Fo - Fc difference map artificially truncated to 3.5  Å resolution calculated from PDB code 1i1q (blue mesh). (b) Simplified medial axis (red) shown within the contoured difference map (blue mesh). In both cases, the map was calculated at 2.7.
