Tutorials

Click-by-click walkthroughs of a complete technique in the SpyDE interface. Each one is generated from the same source as the guided tour built into the app, so what you read here is exactly what the app shows you — open one in SpyDE from Help → <technique> → Guided tour, or read it through here first.

Every tutorial is self-contained: the in-app tour loads its own small example dataset (no download, a couple of seconds), and closes it again when you finish. Each one ends with More information — background on the technique and links to the upstream documentation.

Tutorial	What it covers
First Steps	A quick orientation to SpyDE: the navigator and signal windows, the linked crosshair, per-window toolbars, and the Plot Control dock.
Finding Diffraction Vectors	Detect Bragg peaks across a 4D-STEM scan and overlay the found vectors on the live diffraction pattern.
Virtual Imaging	Place a virtual detector over the diffraction pattern and form a real-space image from what it integrates at every scan position.
Orientation Mapping	Match a simulated template library against a 4D-STEM scan to map crystal orientation, with the best-fit template overlaid live on the pattern.
Strain Mapping	Measure lattice distortion from diffraction-disk positions relative to a reference region, and view it as εxx/εyy/εxy/rotation component maps.
1D Spectroscopy	Navigate a map of per-pixel spectra and watch the spectrum change live under the crosshair — the basic EELS/EDS spectrum-imaging workflow.
