DESCRIPTION OF THE FILES DISTRIBUTED WITH THIS ENTRY
=====================================================

Figures_main:	Contains directories with a brief README and the data to reproduce the figures in the main text, or directions to the relevant directory. For the MD figure, a video is also included. 

Figures_SI:	Contains directories with a brief README and the data to reproduce the figures in the supplemental, or directions to the relevant directory

prototypes:	 Contains the prototypes of barium titanate as well as  a cif for a representation of each of the 27 unique cubic ordered templates of spacegroup 221 with occupied Wyckoff positions: 1a, 1b, 3c. In this representation BaTiO3 is used where Ba occupies the 1a, Ti the 1b, and O the 3c Wyckoff position in the high-symmetry phase.

materials_displacements: This directory contains the output of the pw.x relax calculations of the 4+4 and 2+6 displacement patterns with fixed lattice parameters.

materials_5atom_phonons: This directory contains the phonon calculations for the 5 atom cubic structures

pseudopotentials:	 contains the pseudopotentials used in the calculations
