XtraCrysPy 0.7.5

A Python tool for visualizing atomic systems and properties of condensed matter.

# XtraCrysPy A Python tool for visualizing atomic systems and properties of condensed matter.

Features: - Plot molecular systems with minimal setup - Plot systems from DFT input- or output- files - Interact with the system to caluclate distances, angles, or receive atomic information - Display relaxation steps from QE relax output files - Display reciprocal space features - Plot real space iso-surfaces (charge density, etc) - Plot reciprocal iso-surfaces (Fermi surface, spin-texture, etc) - Band structure and DoS plots from QE or PAOFLOW data - Electron Transport plots from PAOFLOW data

Supported File Types: - Quantum ESPRESSO input or output - POSCAR - CIF (in progress) - XSF - BXSF (coming soon)

Requirements: - python 3.8 - numpy 1.19 - matplotlib 3.5 - [fury 0.8](https://github.com/fury-gl/fury)

Installation (only use –user if you do not have permission to install python packages): - python setup.py install - python setup.py install –user

Usage:

Display an atomic model from inputfile, with the examples/main.py script:

python main.py <inputfile>

Control Inputs:

‘u’ : Toggle UI visibility ‘a’ : Toggle Axis visibility SHIFT + ‘s’ : Take snapshot CTRL + ‘w’ : Exit
