GW band-gap calculation


For GW calculations, my output files currently show band-gap calculations for 5 k-points. Is it possible to change this number? Additionally, I see that my k-points are increasing by an interval of 0.2 for example:

k-point 1: 0.0 0.0 0.0
k-pojnt 2: 0.2 0.0 0.0
k-point 3: 0.4 0.0 0.0
k-point 4: 0.2 0.2 0.0
k-point 5: 0.4 0.2 0.0

Is it possible to change this interval?

Finally, is it possible to plot the GW band structure?


You may change the k points by changing your mesh grid (ngkpt) in your input file. To know exactly which ngkpt is suitable for your calculations you should do convergence study over this parameter.
