EDIFF :: processing powder electron diffraction patterns

• EDIFF package:
  • converts a 2D powder electron diffractogram to a 1D diffractogram (ELD)
  • calculates a theoretical 1D powder X-ray diffractogram (XRD)
  • compares the experimental ELD with the theoretically calculated XRD
• If you use EDIFF in your research, please cite our recent paper:
  • Microscopy and Microanalysis 31, 2025, ozaf045.

Principle

Installation

• Requirement: Python with sci-modules: numpy, matplotlib, scipy, pandas
• pip install scikit-image = 3rd party package for advanced image processing
• pip install pymatgen = 3rd party package employed in PXRD calculation
• pip install bground = our package, interactive background subtraction
• pip install ediff = EDIFF package itself (uses all packages above)

Quick start

• Look at worked example to see how EDIFF in action.
• Download complete examples with data and try EDIFF yourself.

Documentation, help and examples

• PyPI repository - the stable version to install.
• GitHub repository - the current version under development.
• GitHub Pages with help and complete package documentation.

Versions of EDIFF

• Version 0.0 = the 1st drafts, testing of {pxrd} module
• Version 0.1 = the 1st functional version with basic documentation
• Version 0.2 = important improvements of {center} module
• Version 0.3 = {calibration} module + various updates + better ediff template
• Version 0.4 = {center} module: better structure + better funcs + saving coords
