plot_band

Dear EPW users

I want to plot wannierized band structure, hence I added following to my epw.in file.

wdata(1) = 'bands_plot = .true.'
wdata(2) = 'begin kpoint_path'
wdata(3) = 'G 0.00 0.00 0.00 X 0.00 0.50 0.50'
wdata(4) = 'X 0.00 0.50 0.50 W 0.25 0.75 0.50'
wdata(5) = 'W 0.25 0.75 0.50 K 0.375 0.75 0.375'
wdata(6) = 'K 0.375 0.75 0.375 G 0.0 0.0 0.0'
wdata(7) = 'G 0.0 0.0 0.0 L 0.5 0.5 0.5'
wdata(8) = 'L 0.5 0.5 0.5 U 0.25 0.625 0.625'
wdata(9) = 'U 0.25 0.625 0.625 W 0.25 0.75 0.5'
wdata(10) = 'W 0.25 0.75 0.50 L 0.5 0.5 0.5'
wdata(11) = 'L 0.5 0.5 0.5 K 0.375 0.75 0.375'
wdata(12) = 'end kpoint_path'
wdata(10) = 'bands_plot_format = gnuplot'

But it doesn't change my al.win ( do not have wannier_plot = true or something like that) and doesn't create any "gnu" nor "dat" files.

Can anyone please tell me are those "dat" or "gnu" files I should look for to plot the band structure ? If so what is wrong with my input script?

I highly appreciate your answer.

Thank you
Jayangani

Hi Jayangani,

I used the exact same format and it has worked for me. I noticed that your last line should be wdata(13). Maybe this is causing the problem?

Best,
