How to produce an undistorted view of the reciprocal lattice

Here is a short video from  Christian Schürmann to show you how to produce an undistorted view of the reciprocal lattice.

This video walks you through the process of generating unwarped diffraction images in CrysAlisᴾʳᵒ using the Lattice Wizard. Learn how to verify your unit cell, select data runs, and reconstruct reciprocal layers with control over resolution and Miller indices. The demonstration also highlights optional steps like background subtraction and viewing the layer buildup in real-time.

Unwarped images—saved automatically in your experiment’s "unwarped" folder—can reveal subtle features like diffuse scattering, incommensurate peaks, or artifacts such as λ/3 contamination. For users preferring automation, we also show where to initiate unwarping at the end of the data reduction process.
