The povray_settings should be povray-specific parameters. ASE provides interfaces to different codes through Calculators which are used together with the central Atoms object master. This can be used to calculate classical vdW dispersion corrections to a large number of common DFT functionals. Most ASE calculators can be made to generate a file without triggering a calculation using calc. master. You switched accounts on another tab or window. io import extxyz from ase.
