Dear Siesta users,

I am new in using SIESTA. I want to know about Band-structure analysis.

1. What are the script that we have to write in fdf file to get the
   band-structure?
   If I am not mistaken (in user's guide Siesta 3.1) we have to set:
   - WriteBands true
   - BandlinesScale
   - Write block Bandlines
   - write BandPoints

   Are there anythings we have to write?

2. A don't understand about block BandLines and BandPoints, for example, in
user's giude written:

%block Bandlines
1  1.000 1.000 1.000 L
20 0.000 0.000 0.000 \Gamma
25 2.000 0.000 0.000 X
20 2.000 2.000 2.000 \Gamma
%endblock BandLines

Would you mind to explain me what's the meaning that. I mean what's the
meening in first colom. Colom 2 to 4 I think the cartesian coordinate, is
that right? but can anyone explain more detail about this.

And so do the BandPoints, I don't understand too about the number that is
written in %block BandPoints. Where is I get that number (for % block
BandLines and %block BandPoints).

Thank you for your explanation.

Best Regards
