Documentation notice

This documentation was generated with help from a large language model and has not been fully vetted by the developer. Verify critical details against the source code and current application behavior.

What file formats does EWALD support?

• Detector images: .tif, .tiff
• Structure inputs for optics/simulation: .cif, .mcif, POSCAR*, CONTCAR*, *.vasp

How do I calibrate detector geometry?

• Run the managed pyfai-calib2 tool from EWALD.
• Save a .poni file and load it as the active calibrant.
• Apply and confirm corrections before downstream analysis.

What is q<sub>xy</sub>?

• In-plane reciprocal-space axis used for GIWAXS lineouts.

What is q<sub>z</sub>?

• Out-of-plane reciprocal-space axis used with q<sub>xy</sub>.

What is an arch ROI?

• A circular-sector ROI defined by radius and chi bounds for azimuthal extraction.

How do I export fitted peak positions?

• Save the project and use table/export tools in active pages.
• Pole figures and simulation outputs include explicit export paths in their windows.

How do I simulate a candidate structure?

• Use the GIWAXS Simulation tool.
• Load a structure file, choose preset or manual orientation values, and run simulation.

How do I report bugs?

• Open an issue in the repository with:
• EWALD version
• OS/Python version
• Reproduction steps
• error logs
