Installation

pip install vaspvis

Loading Data

from vaspvis import Band, Dos

# Non-HSE Calculation (plain band structure)
bs = Band(folder='path to vasp output folder')


# Non-HSE Calculation (projected band structure)
bs_projected = Band(folder='path to vasp output folder', projected=True)

# HSE Calculation (plain band structure)
bs_hse = Band(
    folder='path to vasp output folder',
    hse=True,
    kpath='GXWLGK', # Path used in calculation
    n=30, # Number of points between with high symmetry points
)

# HSE Calculation (projected band structure)
bs_hse = Band(
    folder='path to vasp output folder',
    projected=True,
    hse=True,
    kpath='GXWLGK', # Path used in calculation
    n=30, # Number of points between with high symmetry points
)

# Density of states (projected or non-projected)
dos = Dos(folder='path to vasp output folder')

Important Note: For spin projected orbitals you must load the spin up and spin down chanels separately using the spin = 'up' or spin = 'down' options with loading data. Default is spin = 'up'. An example of a spin projected band plot is coming soon.
