Hi Weslley,
Thank you very much for your advice!
After reading the manual of Denchar, I found that this code is similar with
rho2xsf. I can also define my own XYZ grid and finally obtain a file, named
.XSF, with the following format.
However, what exactly is the density value for the position, e.g. (2, 0, 0)?
# systemLabel.XSF

Hi, Leila.
You can use the Denchar (one of the Siesta utils) to generate the charge
density distribution. In the input file of you will define the region in the
space that you want to calculate the charge density and the number of
discretization points, so you can build your own XYZ grid and choose the points
that are important.
Good luck!
Yours,
Weslley.
