[Pw_forum] GIPAW: impossible value for nrc

Dear all,
I'm trying to use GIPAW module for NMR calculations.
With the very helpful suggestions of Lorenzo Paulatto I generated the
PAW Pseudopotentials of C and H, including gipaw. With these PP I
performed geometry optimization whithin the cell (calculation='relax')
and subsequently run the "calculation='scf'".
When I try to run gipaw.x module, I always get
from init_gipaw_1 : error # 1
impossible value for nrc
The values for rc, rs,
nrc, nrs, nt, msh(nt) are:
0.000000000000000E+000 0.000000000000000E+000
0 0 1 745
so both nrc and nrs are zero, whereas they are required to be >=1.
I tried also to copy the original PP files into the directory .save
created by pw.x, but with no success.
The gipaw input I used is:
&inputgipaw
job = 'nmr'
tmp_dir =
'/home/nervi/calc/Barbiturico/Michele_periodico/GIPAW_Hex/'
file_reconstruction ( 1 ) = 'H.pbe-paw-gipaw.recon'
file_reconstruction ( 2 ) = 'C.pbe-paw-gipaw.recon'
isolve = 0
iverbosity = 1
q_gipaw = 0.01
spline_ps = .true.
use_nmr_macroscopic_shape = .true.
prefix = 'Hex1'
/
Is there anything that I missed?
Could somebody give yto me further hints on what I have to do?
Thank you in advance,
Carlo
