Figure 4
(a) Slice through a protein crystal, with unit-cell boundaries shown in red and each distinct protein shown in a different color. (d) Slice through a single unit cell, i.e. in the space $[\rho_{\rm {mol}}]$ ( $[{\bf r}]$ ). (b), (e) The unwrapping functions $[{\bf u}_{x}({\bf r})]$ and $[{\bf u}_{y}({\bf r})]$ (red: positive; blue: negative; white: zero). Although the protein is cut off along both x and y, this slice only shows the effect along y. (c), (f) Slices through the replicas $[{\bf R}_{x}({\bf r})]$ and $[{\bf R}_{y}({\bf r})]$ . Each component of $[{\bf u}({\bf r})]$ marks transitions only along its respective axis.
