I am currently using p4vasp for drawing DOS and band-structure plots, but it is not much handy in modifying the OUTPUTS. Could you please suggest any other good software or tools for that?
Another option is Sumo, which is a Python toolkit for plotting and analysis of ab initio solid-state calculation data. It supports VASP, CASTEP and Questaal. Plotting is mostly done through a command-line interface. It can also generate the band paths in the first place. There is also support for plotting phonon bands generate with phononpy.
PyProcar is an open-source Python library providing a set of functions that manage data from the PROCAR file obtained with VASP calculations. It supports VASP, Elk, Quantum ESPRESSO and ABINIT.
PyProcar is capable of performing
- 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
- generating a k-path for a given crystal structure.
