Azimuthal integration using the graphical user interface
Look at your integrated patterns
PyFAI can perform 1D or 2D integration. To view 1D patterns, I will use grace Let’s look at the integrated patterns obtained during calibration.
As you can see, only the 10 rings used for calibration are well defined.
This file is a text file containing as header all metadata needed to determine the geometry.
2D integrated pattern (aka cake images) are EDF images. Try fabio_viewer to see them.
Once again check the header of the file and the associated metadata.
Integrate a bunch of images
We will work with the 20 images used for the calibration.
Start pyFAI-intgrate
Either select files to process using the file-dialog or provide them on the command line.
Set the geometry
Simply load the PONI file and check the populated fields.
Azimuthal integration options
Check the dark/flat/ … options Use the check-box to activate the option.
Do NOT forget to specify the number of radial bins !
Select the device for processing
Unless the processing will be done on the CPU using OpenMP.
Press OK to start the processing.
The generation of the Look-Up table takes a few seconds then all files get processed quickly
Run it again to perform caking
Same a previously … but provide a number of azimuthal bins !
Visualize the integrated patterns
Once again I used grace and fabio_viewer to display the result.
That’s all.
