We present two modules that expand functionalities of the all-electron full-potential density functional theory package WIEN2k for computation Chern and $Z_2$ topological invariants. Characterization properties relies on methods: computing an evolution hybrid Wannier charge centers insulators (construction maximally localized functions is not needed) Berry phase a multitude Wilson loops discretize 2D Brillouin zone as well mapping curvature. The implementation validated by testing well-known materials feature topologically non-trivial electronic states.
