Experiments in a saved project

The saved experiment supplies measured data or a calculation range, instrument settings, peak profile, background, exclusions and links to structures. Commands use these settings when loading the complete project.

Prepare the experiment

Use the application experiment controls or Python experiment objects to import observations and configure the experiment, then save the project.

The command line operates on that saved experiment. It does not create an experiment from a raw pattern file or offer a second set of instrument and background options on the fit command.

Choose the run

  • Calculate evaluates the model, including experiments with simulation ranges.
  • Fit uses measured observations and the fitting mode saved in the project.

Use --dry when you want to calculate or fit without writing project changes. It still executes the calculation or fit.

The shared Experiment stage explains the model, and fitting modes explains single, joint and scan analyses.
