[Pw_forum] obtain k-point for band structure calculation

[ehsan targholi]

Dear Hadi
thanks a lot for your reply. do you mean i use of automatic K-point in
bands calculation?
when i do this, the band.ps could not open with Ducument viewer in linux.
and i dont know another way to show result. if  it is possible for you,
please send one proper input for band calculation. is any way to plot the
result of band structure calculation with excel other simple software?



best regard & thanks
