Hi everyone,

when computing Wannier funciton centers in periodic boundary conditions, the centers are often localized outside my simulation box. Can I just map them into the box / are they also periodic?
Also, for the Wannier function centers I get a file containing their xyz coordinates and another value in a fourth coulumn. What is this value? I could not find a hint in the manual. Does it describe how well the localization worked / how "local" the wannier funciton finally is?

Many thanks in advance and best
Thorren

Hi

yes, Wannier centers also follow PBC.
The forth column is the spread (2nd moment) of the function.
