[Wannier] Wannier Digest, Vol 87, Issue 14

[Olivia Irving]

Hi, 
I am using the latest version of Wannier90. I have attached my input files. 
By adding noncolin=.true. 
lspinorb=.true.
to my quantum espresso files I got rid of the spinor projection problem but for some reason even though I have asked for nosym=.true. 
the program somehow reduces the number of kpoints . Due to the fact that I have 27 kpoints in my nnkp file I believe the source of this is quantum espresso. 
If you have any suggestions on how to get the kpoints to match your help would be greatly appreciated. I am using the kmesh utility. 
Thanks

Olivia,

 If you are using the latest wannier90 (2.0.1) and pwscf (5.1.x) then everything should work fine. If not - post your input files so we can reproduce the problem.

 If you have an older version of pwscf (5.0 series) then you need to update the version of pw2wannier90.f90 see the file ./pwscf/REAME the wannier90 distribution. 
 I don?t recommend using older versions of wannier90 or pwscf to compute spinor wannier functions.

Yours
  Jonathan
