[Wien] Help on Fermi Surface Plotting

[Alex Animalu]

Dear Wien2k Users,
I am very new to WIEN2K and want to plot the Fermi surface following the instructions given in the UG. My question is on how to determine the x-len and y-len of the two directions of the plane (in bohr^-1). The UG said that this can be found in case.spaghetti_ene. Which line is this number located? Assuming my case.spaghetti_ene with total bandindex of 22 with the first band index is as shown below, how do I determine these two values from the data?
  bandindex:           1
