Article on ZENODO: VASProcar: Python tools for DFT calculations

VASProcar is an open-source package written in the Python 3 programming language, which aims to provide an intuitive tool for the post-processing of the output files produced by the DFT VASP or QE code, through an interactive user interface.

VASProcar extracts information and results from the following VASP output files (CONTCAR, KPOINTS, OUTCAR, PROCAR, DOSCAR, LOCPOT, PARCHG and vasprun.xml) or QE output files (scf.in, scf.out, nscf.in, nscf.out, bands.in, bands.out, projwfc.in, projwfc.out, "filband", "filproj".projwfc_up and "filpdos".pdos_atm#_wfc).
