Bandstructure of Si in GW

Dear all,
I downloaded an example for GW bandstructure from http://cms.mpi.univie.ac.at/wiki/index. ... WANNIER90). I followed the guide provided on this website, installed the wannier90 and also recompiled the VASP for the vasp2wannier90 interface, but did not got the expected result. At the third step, no input files for wannier90 runs (inculdes wannier90.amn, wannier90.mmn, wannier90.eig ) are generated.
Here are the INCAR and the output file. Wolud anyone please help me ?

INCAR---------------------------
## Step 1: default PBE
ISMEAR = 0
SIGMA = 0.05
GGA = PE
##

## Step 2: virtual orbitals
#ISMEAR = 0
#SIGMA = 0.05
#GGA = PE
#
#ALGO = Exact
#NBANDS = 64
#LOPTICS=.TRUE.
#NEDOS=2000
##

## Step 3: GW + WANNIER90
#ALGO = GW0 ; LSPECTRAL = .TRUE. ; NOMEGA = 50
#NBANDS=64
#LRPA = .FALSE.
#LWANNIER90=.TRUE.

| Use PRECFOCK to select the mode for HF type calculations |
| PRECFOCK= L low (coarse grid for HF, normal augmentation charge) |
| PRECFOCK= M medium (normal grid for HF, normal augmentation charge) |
| PRECFOCK= F fast (coarse grid for HF, soft augmentation charge) |
| PRECFOCK= N normal (PREC=N grid for HF, soft augmentation charge) |
| PRECFOCK= A accurate (PREC=A grid for HF, soft augmentation charge) |
| |
| L is equivalent to ENCUTFOCK=0 in vasp.5.2.2 |
| M is equivalent to vasp.5.2.2 if ENCUTFOCK is not set |
| M&L cause significant noise in the forces and are no longer recommended |
| |
| N is recommended for routine calculations, little noise to be expected |
| A accurate is now recommended for very accurate calculations |
| F fast is now recommended for quick calculations (even phonons often ok) |
| (speedup between 2 and 4) |

you have to uncomment the LWANNIER90 tag in INCAR

I uncommented the tag in the next step. I have solved this problem by recompiling the VASP. Thank you anyway.

I am also facing the same problem, have you used some different trick while recompiling the vasp? Please let me know.

Hi,
Can you please let me know, while recompiling the Wannier, have you used some trick?
best regards,
