Dear Dr. Postnikov.

Sorry I have made an mistake, What I mean that:
When I choose subblock # 0 = 1.0 and subblock # 1 = -1.0, I got the result
same as when I choose subblock # 0 = 1.0 and subblock # 1 = 1.0.

The result is the plot of charge density like your picture in page 28 in
your slide (visualization and post-processing tools for siesta).

Previously, I hope that I will got the profil of spin density when I
choose subblock # 0 = 1.0 and subblock # 1 = -1.0, as you said in the
slide, page 26. "Choose 1.0 and 1.0 for plotting the charge density,1.0
and −1.0
for plotting the spin density".

I am new in computational field. Please give me a clue.


Thank you

Best Regards

Yuly Kusumawati
