### Re: Bader Charge analysis

Dear Professor, This is what striking me for a long time. As you see I have three different values of bader charges for three different commands for the same compound and for the outfiles of same calculation. 1. bader -b weight CHGCAR 2. bader CHGCAR -ref CHGCAR_sum 3. bader -b weight CHGCAR -ref CH...

### Re: Bader Charge analysis

Dear Professor, Is it also necessary to get total(Valence+core)electrons equal by doing bader CHGCAR_sum only in ACF.dat and sum of all (valence + core) electrons on all the atoms. At beginning i get confused with this step that i tried to match number of electrons in this way and keep on increasing...

### Re: Bader Charge analysis

Dear Professor, When i issued bader -b weight CHGCAR -ref CHGCAR_sum I got the value of charge on ACF.dat file as follows. As you said -b weight method is more accurate. Now let's calculate charge transfer on each atom. We have the formula to calculate charge transfer as: Charge transfer or Net bade...

### Re: Bader Charge analysis

Dear Professor,

So in this case I don't need further calculations increasing FFT for convergence, right ?

### Re: Bader Charge analysis

Dear Professor,

I attached my files here. I have issued bader -b weight CHGCAR -ref CHGCAR_sum.Please let me know if i need to do further FFT grid convergence calculation or not. I am not able to attach files here. So i sent your email. Later you can paste my files here.

### Re: Bader Charge analysis

Dear Professor, I am able to get equal number of electrons in ACF.dat and total ZVAL even with default FFT, I mean without increasing its value. Finally, I want to understand that how and when we could be confirmed that our FFT values are converged? If the default values are giving correct charge tr...

### Re: Bader Charge analysis

Dear Professor,

I want to do convergence of bader charge on each atom by increasing fft. Here also, I have never achieved total electrons in ACF.dat file equal to total ZVAL for all atoms though I keep on increasing FFT in each step by 50%.

### Re: Vacancy migration frequency

Dear Professor,

Can we use the INCAR tags to run vibrational frequency like IBRION = 5 or 6 in the same NEB run. Also Do we need to set selective dynamics like calculating mode in one direction like z.

Dear Professor,

In that sense can I run G-SSNEB, CI-NEB in VASP just only by making images by nebmake.pl without compilation ?

### VTST compilation

Dear admin, I have seen in VTST manual that we have to compile VTST code in order to run NEB in VASP. But i have been running NEB without compilation in VASP. I first make images with nebmake.pl and run NEB calculation in VASP with relaxation of the images. and then i extract energy value for each i...

### Re: Bader Charge analysis

Dear Professor,

Some of the elements like Sb, Zn do not have _sv or _pv potential but have _sv_GW or _pv_GW. In that case , can we use _GW potential to calculate charge transfer.

Sincerely,

DT
