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.
