New in release (0.9) [15/05/2020]¶
PyPI release! Can now install with
pip install matador-db(unfortunately
matadorwas taken, but they are sufficiently orthogonal that the package name
matadoris retained here.
Much improved code structure and many additional classes that wrap the raw calculation dictionaries for e.g.
matador.crystal.Crystaland spectral classes.
matador.ormcontaining useful models for data handling.
matador.orm.orm.DataContaineras a base class that allows for easy access to underlying dictionaries.
matador.orm.spectralmodule that contains many useful classes for manipulating and plotting e.g. bandstructures, DOS and finite temperature properties.
New features in
Pseudo-ternary phase diagrams (building towards arbitrary n-dimensional phase diagrams).
matador.hull.EnsembleHullclass and submodule to support the Bayesian Error Estimate Functional (BEEF) and finite temperature phase diagrams.

Finite temperature hulls based on
Refactored old PDF similarity module into new module
Added new fingerprint class,
matador.fingerprints.PXRD, with associated plots (thanks for James Darby for some initial code). Defaults calibrated with GSAS-II.
