Tutorials
Each tutorial teaches one analysis on one example: its structure, its measured data and the steps from a first calculation to a fitted model and its report. Every example has a tutorial for each interface, and they teach the same steps in the same order:
The table lists every tutorial, grouped into sections, with the example's tags. See Experiment types and labels for the tags.
All purposes Fitting measured data Calculation without measured data
All fitting modes Fit several experiments together Fit a scan using the preceding result Fit one experiment
All sample forms Powder diffraction Single-crystal diffraction
All probes Neutron diffraction X-ray diffraction
All beam modes Constant wavelength Time of flight

Understand the reference
An example may compare a calculated curve or fitted values with FullProf or another reference. Read what is being compared: identical model settings, a program-specific model, or a labelled regression result answer different questions.
Use fit quality to interpret agreement factors. The references validate the paths and cases they cover; they do not establish every possible model or interface operation.
