You can use AIMAll (http://aim.tkgristmill.com/index.html), AIMPAC (http://www.chemistry.mcmaster.ca/aimpac/). Another option is MultiWFN http://multiwfn.codeplex.com/, which is very powerful and not limited to the analysis of electron density. However, these files look unfamiliar to me. Are they binary or text files?

Thanks a lot. I will try to understand these tools/softwares...

thanks again Marat Talipov

You need ACF file, column CHARGE. These are charges of your atoms defined by countor of minimal gradient around each atom.

Hi,

The step by step procedure to perform the Bader charge analysis using VASP and charge density difference plot using VESTA is clearly explained in a Youtube channel. You can find it here:

Please look this video link to calculate bader charge
