DScribe is a Python package for transforming atomic structures into fixed-size numerical fingerprints. These fingerprints are often called “descriptors” and they can be used in various tasks, including machine learning, visualization, similarity analysis, etc. To get started you can check the basic tutorial.

Note

Version 1.2.0 adds the Valle-Oganov descriptor and derivatives for the Coulomb matrix. Check the changelog for more details.
