EDIFF :: processing of powder electron diffraction patterns

• EDIFF is under development, but key modules do work:
  • io = input/output data treatment
  • background = background subtraction
  • center = find center of 2D powder diffraction pattern
  • radial = calculate radial distribution (2D-pattern ⇒ 1D-pattern)
  • pxrd = calculation of theoretical powder X-ray diffraction patterns
• If you use EDIFF in your research, please cite the OpenAccess paper:
  • Materials 14 (2011) 7550. https://doi.org/10.3390/ma14247550
  • The paper describes {stemdiff} package, {ediff} is a part of it.

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

• See how it works:
  • Look at worked example in Jupyter.
• Try it yourself:
  • Download complete examples with data and scripts and basic instructions.
  • After downloading, unzip it and follow the instructions in readme file.

Documentation, help and examples

• PyPI repository.
• GitHub repository.
• GitHub Pages with documentation.
