Experiments¶
Select or create an experiment¶
On Experiment → Main, expand Experiments and select a row. Load experiment reads one or more experiments from CIF or .edi files, each with its type, settings and any measured data. Create experiment adds a starting experiment linked to the project's structures.
Use experiment types and labels to distinguish sample form, probe and beam mode. Choose the measurement type before importing measured data. Until data are loaded, the experiment uses a simulation range. A project can contain measured experiments and simulations; fitting uses the measured data.
Load a powder pattern¶
Create or select an experiment first. Open Load ▾ and choose From file… under Measured data. Text files may contain x y or x y sigma columns separated by spaces, tabs or commas.
| Measurement | x axis |
|---|---|
| Constant wavelength | 2θ in degrees |
| Time of flight | Time in microseconds |
Check the import message for skipped or adjusted rows. After loading, the measured points define the range and the experiment type is fixed. Instrument, profile, background and exclusions are retained. Use the same Load ▾ → Measured data → From file… route to replace the data; Undo restores the preceding state.
