Where can I get the current version?
Use the latest stable release on GitHub. The Dioptas overview shows the current version and links to the manual, source code, and Python package.
The standalone applications include their dependencies. The macOS application targets Apple silicon; for an Intel Mac, use the Python installation described in the installation guide.
Can I use my own calibrant?
Yes. The calibration manual describes adding a text file of d-spacings to the application’s calibrants directory. The location depends on how Dioptas was installed. Keep a separate copy of custom calibrant files so that an application upgrade does not replace your only copy.
What should I include in a bug report?
First check whether the problem also occurs with the current stable release. Then open an issue on GitHub with:
- The Dioptas version, operating system, and whether you use a standalone application or a Python environment.
- The steps needed to reproduce the problem and the full error message or traceback.
- A small example image or project, if it can be shared, and a screenshot when useful.
For a Python installation, starting dioptas from a terminal can help capture diagnostic output. Back up project and configuration files before trying changes to an existing installation.
How do I check a calibration?
Inspect the detector image, azimuthal cake, and integrated pattern together, comparing the observed reflections with the chosen calibrant. Confirm the detector pixel size, wavelength, and image orientation. The calibration manual explains the controls and how to save and reuse a calibration.
Can I process data without opening the interface?
Yes. The headless scripting API can load a saved .dio project and integrate images in a Python script. The project overview includes a short example.
