[Wien] xcrysden to plot Fermi surface

[Yundi Quan]

Dear Sir/Madam,
My question may not be directly related to WIEN2k. When plotting Fermi
surface using XCrysden, it says that case.in1 should be changed into
unit 5. But if I change case.in1 to unit 5, I would always get an
error message saying that kpoints in case.in1 is inconsistent with the
kpoints in case.kgen. Should case.in1 be changed into unit 5?
