Hi, all,(adsbygoogle = window.adsbygoogle || []).push({});

I want to calculate the band structure and there is example such like that:

BandLinesScale pi/a

%block BandLines # These are comments

1 0.000 0.000 0.000 \Gamma # Begin at Gamma

50 2.000 0.000 0.000 X # 25 points from Gamma to X

20 2.000 1.000 0.000 W # 10 points from X to W

30 1.000 1.000 1.000 L # 15 points from W to L

40 0.000 0.000 0.000 \Gamma # 20 points from L to Gamma

50 1.500 1.500 0.000 K # 25 points from Gamma to K

20 1.000 1.000 1.000 L # 15 points from W to L

30 2.000 0.500 0.500 W # 10 points from L to U

20 2.000 0.000 0.000 X # 25 points from U to X

Is there anyone can tell me how to define the number of the points and the coordinate of these points? thank you very much

Yours,

Lucy
