QTAIM analysis of QS density

[Tobias Kraemer]

Hi all,


I am aware that the topic of this post has come up on this platform in the 
past, nonetheless I would like to bring it up once more. 
Being interested in QTAIM analysis (often referred to as Bader analysis) of 
the electron density, I was wondering if it was in the
meantime possible (although I believe this may not be the case) to generate 
the appropriate (density) files in some way from QS
calculations. Has anyone been successful to generate some form of wave 
function file (.wfn, here is a link to its general format
http://aim.tkgristmill.com/wfxformat.html) from a density cube, which could 
be processed by any of the available codes for such
analyses? There was a mention of the "bader code" from the Henkelman group, 
and I wondered if some of you have had some
success in interfacing this code with CP2K. I guess what I would have in 
mind would be to perform a geometry optimization of 
my system of interest in the solid state and subsequently obtain an AIM 
plot from the density. Of course there are all sorts of 
issues here with the pseudo-potential approach, but this aside, I would be 
happy to hear about people's recent experiences with
this, provided that someone has looked into this approach at all.

Your comments are much appreciated.


Kind regards 

Tobias
