PyProcar#

PyProcar is a robust, open-source Python library used for pre- and post-processing of the electronic structure data coming from DFT calculations. PyProcar provides a set of functions that manage data from the PROCAR format obtained from various DFT codes. Basically, the PROCAR file is a projection of the Kohn-Sham states over atomic orbitals. That projection is performed to every k-point in the considered mesh, every energy band and every atom. PyProcar is capable of performing a multitude of tasks including plotting plain and spin/atom/orbital projected band structures and Fermi surfaces- both in 2D and 3D, Fermi velocity plots, unfolding bands of a super cell, comparing band structures from multiple DFT calculations, plotting partial density of states and generating a k-path for a given crystal structure.

Currently supports:

  2. Quantum Espresso

  3. Abinit

  4. Elk (Band Structure and Fermi in development)

  5. Lobster (Stll in development)
