Bader Charge Analysis Problem

[Trivanni Yadav]

Hello,

I have just started using Bader Charge, and this is my first time being on this forum.

As per the instructions, I first unpacked all the required files (for instance, Bader binary files, source code files, and chgsum.pl script). I ran electronic SCF calculation by adding these tags to my INCAR file:

LAECHG = .TRUE.
NSW=0
LWAVE = .FALSE.
LCHARG = .TRUE.


After it generates AECCAR0, AECCAR1, and AECCAR2 files. My system has 192 atoms. So, by using the chgsum.pl script to generate the CHGCAR_sum file, I received this message:

```
Atoms in file1: 0, Atoms in file2: 0
Points in file1: 7.1966367651e-06, Points in file2: 7.1966367651e-06
```

Which doesn't make sense to me, since I checked all my files along with the CHGCAR files, they have correct dimensions and the file is complete. Then I tried to use Bader:

```
./bader CHGCAR -ref CHGCAR_sum
```

I received this message:

```

Can someone possibly help me with this issue? I really appreciate any possible suggestions.

if you can make the two charge density funds, I can take a look at the problem.

Note: actually include the AECCAR0 and AECCAR2 files.

Dr. Henkelman,

I would like to provide an update to my post.

I attempted to use "./bader CHGCAR" directly, and it executed successfully, generating ACF.dat, AVF.dat, and BCF.dat files. These files seem to be yielding meaningful results.

It appears that there might be an issue with the chgsum.pl script. Additionally, the download link provided on the webpage seems to be malfunctioning. Every time I attempt to access it, it fails to load. Consequently, I obtained the script from GitHub. However, I cannot ascertain its accuracy.

try downloading our scripts from https://theory.cm.utexas.edu/vtsttools/download.html ; UT has recently restricted http access vs https, but you should be able to download our scripts from that link.

I clicked on this link and then attempted to access the available vtst tar files. Unfortunately, nothing seems to work. The link is not working :(

Dr. Henkelman,

Great News!!
The link works. I had to copy the link first and then paste it into a new tab, and then it downloaded successfully. The script works absolutely fine. Thank you so much! :)

good; I was going to suggest things like clearing your history and refreshing, ... but I assumed that it would sort itself out
