[Wannier] hi, I would like to ask how to generate *.xsf file?

[r95222066 at ntu.edu.tw]

          I check my Batio3.pw2wan input flie. I have write_unk =3D  
.true. It =20
     had generated UNK*,but still no Batio3.xsf file.
     Here is some top lines of my UNK00001.1
     --------------------------------------------------------------------------
        27          27          27           1          20
       (-3.114419060730155E-003,4.802028170665693E-004)
       (-3.796548945615000E-003,5.853783525116031E-004)
       (-5.463592130836901E-003,8.424146787488749E-004)
       (-6.765393752372161E-003,1.043135517464266E-003)
      
----------------------------------------------------------------------------
         I read Batio3.bxsf file,all eigenvalue are smaller than zero (the =20
     fermi energy default value is just 0). Is that the reason that I can't =20
     open my Batio3.bxsf file? I also view the comment of bsxf format in =20
     Xcrysden website.There is nothing different at all.
        Here is my Batio3.bxsf.It is strange for the bands value are almost =20
     a constant equall -0.34633858E+02.

         Here is my Batio3.win file.I think maybe it is something wrong.but =20
     i'm sure the KPOINTS is the same as Batio3.nscf file.
