Lesson 8 of the Profex workshop at the Forschungszentrum Jülich, Germany, in March 2024 discusses some common refinement challenges. The first example provides information about how texture / preferred orientation is refined in Profex. The second example demonstrates how to refine anisotropic crystallite sizes. The third example shows how to create electron density maps (difference Fourier maps), and how they can help with structure refinements.
