I'm not fully familiar with the w2wannier flow, but I can see from the def file, that the $file.vector file already has a $hf option.

However, then it should probably be also in the $file.energy$hf line

and I also see a required $file.fermi file (I don't know when it is created), but that should also relate to a hf calculation.

So I suspect that only copying the vectorhf file will not be enough.

Regards

Dear Nilofar, Oleg, and Peter,

I cannot say for sure whether w2w will work with HF because I have
never tried it, and do not know too much about how an HF calculation
works in Wien2k.  If, as Peter says

I can confirm that case.vectorhf  has the same structure than
case.vertor.

it should probably work out.  Nilofar, maybe you can give it a try and
report back here -- I would be interested to know, and if problems do
turn up, I will try to help.

For testing one could simply   copy   case.vectorhf case.vector and
try it out.

For w2w, I believe the ‘-hf’ switch should be enough.

I don't know if there are any other input files requires for w2w or
BerryPI (case.energy ?   there is also a hf file), ...

Looking at the w2w.def file

   5,'$file.inwf',            'old',    'formatted',  0
   6,'$file.outputwf$updn',   'unknown','formatted',  0
   7,'$file.amn$w90updn',     'unknown','formatted',  0
   8,'$file.mmn$w90updn',     'unknown','formatted',  0
   9,'${scratch}$file.vector$sc$hf$soupdn', 'unknown','unformatted',9000
  10,'$file.nnkp',           'old',    'formatted',  0
  12,'$file.eig$updn',       'unknown','formatted',  0
  18,'$file.vsp$updn',        'old',    'formatted',  0
  20,'$file.struct',         'old',    'formatted',  0
  50,'$file.energy$soupdn',   'old',    'formatted',  0
  51,'$file.fermi$updn'       'old',    'formatted',  0

only ‘vector’ and ‘vsp’ is needed in the “normal” case.  What is there
in the ‘hf’ file?

 From BerryPI perspective, you can probably do the onsite hybrid
functional the same way as the orbital potential (LDA+U). The
flow of "runsp_lapw -eece" looks similar to "runsp_lapw -orb".

“Onsite hybrid”/EECE is quite a different beast than “full hybrid”,
and I believe it should pose no problems to w2w/BerryPI.  Just run
lapw1 with the appropriate switches (‘-orb’?).
