+# Dans_Diffraction
+## Structure Files
+A selection of CIF and mCIF files for use as examples in Dans_Diffraction.
+
+Structure files are from a range of sources including online databases, publications and many are generated by the
+author using a range of software. Most of the structures are in no way related to the author and are provided as
+useful examples.
+
+### Instructions
+```text
+$ ipython -i -m Dans_Diffraction
+```
+
+```python
+>> import Dans_Diffraction as dif
+>> print(dif.structure_list.list) # display all available files
+>> xtl = dif.structure_list.Diamond() # create crystal object
+>> xtl.info() # print Crystal structure parameters
+```
+
+Full code documentation available [here](https://danporter.github.io/Dans_Diffraction/).

+
+### CIF & mCIF
+Crystallographic Information Files (CIF) are the standard definition of crystalline structures used in crystallography.
+A variant on these, mCIF, are used to define magnetic structures.
+
+### Datasources
+The files are downloaded or generated from a range of data sources, for example:
+
+* [ICSD](https://icsd.products.fiz-karlsruhe.de/)
+* [AMCSD](http://rruff.geo.arizona.edu/AMS/amcsd.php)
+* [MAGNDATA](http://webbdcrista1.ehu.es/magndata/)
+* [ISODISTORT](https://stokes.byu.edu/iso/isodistort.php)
