WannierIO.jl

Appearance

WannierIO.jl ​

A Julia package for reading and writing Wannier90 file formats.

The package is intentionally minimal so the IO layer can be reused in other Wannier and electronic-structure tooling.

This package originates from the IO part of the Wannier.jl package.

What you can do ​

  • Read/write core Wannier90 formats (win, amn, mmn, eig, chk, UNK, spn, ...)

  • Read/write tight-binding datasets (*_tb.dat, *_wsvec.dat, *_hr.dat, *_r.dat)

  • Read/write volumetric formats (xsf, cube, bxsf)

  • Store tight-binding operators in sparse/compressed backends (HDF5/JLD2/Zarr)

Quick start ​

julia
using WannierIO

amn = read_amn("silicon.amn")
write_amn("silicon_copy.amn", amn.A; header=amn.header)

tb = read_w90_tb("silicon_tb.dat")
write_w90_tb("silicon_out_tb.dat", tb)

Documentation map ​

  • Introduction: read/write workflows, tight-binding reduction, sparse storage.

  • API reference: conventions, utility types, Wannier90/TB APIs, volumetric and EPW helpers.
