Dear Wein2k users,
i have successfully runs the Spaghetti calculations after getting spin
polarized scf convergence using following commands for 16 atomic based
primitive unit cell,
x lapw1 -band -c up/dn
x irrep -up/dn
x lapw2 -band -qtl -c -up/dn
Edit case.insp
x spaghetti -up/dn
I need clarification on the below two questions
*First question,*
I want to plot the data from the band structure using my own plot program.
I have seen the details of earlier mailing list which guides how to plot
the band structure using the output data files. In one of the mailing list
it was suggested that "case.bandsup/dn.agr" gives the output data to draw
plots using our own software packages. But, in this file format the data is
written in three columns. It is understood that first and 2nd column
represents K-data and Energy (ev) data respectively for each band (given
by the band index). But, 3rd one give some numbers named under character.
what is the meaning of these number in the 3rd column in the
case.bandsup/dn.agr file.
Similarly, in a band character plot using "case.qtlup/dn" file, for a
primitive system of 16 number of atoms it gave total 15 number of columns
for a given Band index (first column is energy in Ry, 2nd column is index
of atoms, 3-15 columns for tot,0,1,px,py,pz,2,Dz2,Dx2-y2,Dxy,Dxz,Dyz,3).
Here, in the 2nd column i have found an extra atomic number as 17 and
corresponding K value at 3rd column (tot) while other columns (4-15) are
empty. This value for K are meant for total where is it represented by 0
atom index in the DOS calculations, is n't it ?
Further, i have not understood the format of other files such as
case.energyup, case.ouput1up, case.spaghettiup_ene...can any body give
the reference/link where formats of these files explained properly as
wein2K user guide explains the format of input files.
*Second Question,*
Though i have run successfully, x irrep -up/dn and x lapw2 -band -qtl -c
-up/dn , i have not found any colours for the band in the band structure
plot when plotted with wein2k itself. In the below i have given the details
of "case.insp" file which is input for Spaghettiup/dn.

can anybody help me out to sort out this problem
thanks in advance and looking forward to your replies,
