vise

VASP Integrated Supporting Environment (vise) is a collection of tools that supports VASP users to prepare input files for the VASP calculations, handle its calculation errors, and analyze its results.

Note1: Only ensure VASP ver5.4.4 or later so far.

Note2: Units used in pydefect are eV for energy and angstrom for length following the vasp convention.

Note3: When transforming the structure to the primitive one, antiferromagnetic magnetization is not supported.
