## Task

Visualization of BSE eigenvectors using fatbands.

## Input

Si 5.4300 0.5 0.5 0.0 0.0 0.5 0.5 0.5 0.0 0.5 2 cart 0.00 0.00 0.00 0.25 0.25 0.25

### INCAR

- This is the INCAR file for the basic DFT calculation:

System = Si PREC = Normal ; ENCUT = 250.0 ISMEAR = 0 ; SIGMA = 0.01 KPAR = 2 EDIFF = 1.E-8 NBANDS = 16 LOPTICS = .TRUE. # needed for WAVEDER file LPEAD = .TRUE. OMEGAMAX = 40

### KPOINTS

The KPOINTS file will be automatically generated in this example.
