Dear Thorren, 

you can directly calculate the Wannier centers and it’s associated centers within CP2K via: CP2K_INPUT <https://manual.cp2k.org/trunk/CP2K_INPUT.html> / FORCE_EVAL <https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL.html> / DFT <https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT.html> / LOCALIZE <https://manual.cp2k.org/trunk/CP2K_INPUT/FORCE_EVAL/DFT/LOCALIZE.html> 

Greetings, 
Thomas

How exactly the "center of an orbital" is defined is to some extent arbitrary, e.g., it could be the point in space of maximum density or a wannier funciton center or any other definition that makes sense. Is there a straightforward way to calculate such a property, either within CP2K or with a suitable post-processing tool?
