Terminology

This page provides definitions of common abbreviations, parameter names and data formats used in EasyDiffraction.

Input/Output data format

EasyDiffraction uses the Crystallographic Information File (CIF) format for both input and output. CIF is a widely used, human-readable format for crystallographic data, as specified by the International Union of Crystallography (IUCr)

If certain experimental data is not covered by standard CIF dictionaries, EasyDiffraction introduces custom CIF keywords, which are defined below.

Glossary

Below are common abbreviations used in the documentation and tutorials.
