pyFAI scripts manual

While pyFAI is first and foremost a Python library to be used by developers, a set of scripts is provided to process a full diffraction experiment on the command line without knowing anything about Python. Those scripts can be divided into 3 categories: pre-processing tools which prepare the dataset for the calibration tool. The calibration is the determination of the geometry of the experimental setup using Debye-Scherrer rings of a reference compound (or calibrant). Finally a full dataset can be integrated using different tools targeted at different experiments.

Pre-processing tools:
  • pyFAI-drawmask: tool for drawing a mask on top of an image (deprecated)
  • pyFAI-average: tool for averaging/median/… filtering images (i.e. for dark current)
Calibration tools:
  • pyFAI-calib2 and pyFAI-calib: manually select the rings and refine the geometry
  • pyFAI-recalib: automatic ring extraction to refine the geometry (deprecated: see “recalib” option in pyFAI-calib)
  • MX-calibrate: Calibrate automatically a set of images taken at various detector distances
  • check_calib: checks the calibration of an image at the sub-pixel level (deprecated: see “validate” option in pyFAI-calib)
Azimuthal integration tools:
  • pyFAI-integrate: the graphical interface for integration (GUI)
  • pyFAI-saxs: command line interface for small-angle scattering
  • pyFAI-waxs: command line interface for powder difration
  • diff_map: diffraction mapping & tomography tool (command line and GUI)
  • diff_tomo: diffraction tomography tool (command line only)
