Figure 7
Unbending. (a) A perfect 2D lattice would have a unit cell at each lattice point. In practice, macromolecules in images of 2D crystals are imperfectly ordered. The lattice disorder in (b) is exaggerated, but small distortions can be found by cross-correlation and corrected by non-linear interpolation of the image. Disorder correction greatly improves the resolution obtainable from such samples. |
