An error in band structure unfolding with spin_polarized

Hi,

I followed the example of the tutorial for Band structure unfolding but added

SpinComponents = spin_polarized
KPointsUseTimeReversal = no

An error occurs saying

At line 386 of file utils/unfold.F90 (unit = 10, file = '././unfold_gvec.dat')
Fortran runtime error: End of file

The source file from lines 382-389 reads (I use Octopus 11.1)

file_gvec = io_open('./unfold_gvec.dat', global_namespace, action='read')
read(file_gvec,*)
read(file_gvec,*)
do ik = 1, st%d%nik
  read(file_gvec,*) vec_sc(1:3)              ! <- This is line 386
  call kpoints_to_absolute(sys%kpoints%latt, vec_sc(1:sys%space%dim), gvec_abs(1:sys%space%dim, ik))
end do
call io_close(file_gvec)

I found the problem is that st%d%nik=34 with spin_polarized, however there are only 17 rows of data in unfold_gvec.dat (path_kpoints_grid%npoints=17). So the error occurs when the code tries to read the 18th row of the data.

Did I use the band structure unfolding utility by mistake, or should I not use it with spin_polarized?

Thanks a lot!

Best regards,

Xiaosong

P.S. If I would like to get the unfolded band structure. Would it be possible if I change the code a little bit so that I read each of the 17 rows of data for two different spins, respectively?
