Click the Launch Binder badge to start a Docker image. Wannier90 is included as a library in ABINIT and the process is automatic, so that in a single run you can do both the ground state calculation and the computation of MLWFs. Since ABINIT is based on periodic boundary conditions, every wavefunction is characterized by a wavevector, usually denoted k-point. However, very often, it is needed to run calculations for dozens or hundreds of q-points. If you have run the command make in the Abinit main directory, and everything went well, then you have obtained the abinit program and all the accompanying program, in particular cut3d.
