[Wien] Reg: 2D Fermisurface plots

[Swetarekha Ram]

Dear Prof. Blaha and Wien2k users,

                    Can any one help me how to plot 2D Fermi surface. My
system is the cubic system, so I am using the the script  sc_fs_mesh as
available in wien2k. I tried according to the manual, but I have the doubt,
that how  to give x-len and y-len on the top of the case.spaghetti_ene file.

I have seen the previous mailing list, where some people asked the same
doubt.
According to those mail explanation , I am thinking my x-len = 0.33907, But
what about my  y-len value?
If I am taking the x-len and y-len values = 0.33907 like below , I am
getting error:
16, 11, 0.33907,?, 31,21,0,0
error reading file. Propably wrong mesh

Here I am attaching  the few lines of my case.spaghetti_ene and the
case.klist file,



and my case.klist file is like
 1    0    0    0   60 1.00-7.00 1.50       16  11
         2    0    0    1   60 1.00
         3    0    0    2   60 1.00
         4    0    0    3   60 1.00

        15    0    0   14   60 1.00

and case.spaghetti_ene file is like
