[CP2K-user] [CP2K:16485] Orbital Density

[Thorren Kirschbaum]

Also, I have an input in which the atoms are all located in a cubic cell, 
with periodic boundary conditions in all three dimensions. The Wannier 
funciton centers are then placed outside my cell. Can I just move them 
inside the cell by adding/subtracting the lattice constant / can they also 
be regarded to be periodic?

Many thanks in advance and best
Thorren
