[Pw_forum] Problem to run GIPAW

Dear all

I tried to run GIPAW module to calculate the nmr chemical shift and epr
parameter but I had some problems:

If a tried to calculate 'efg' - electrical field gradient, everything goes
fine.
But if I tried other options like 'nmr', 'g_tensor', 'f_sum' I got the
following error:

It looks like threre is a problem in the routine to compute the magnetic
susceptibility, which
is a common routine to both calculations. How can I solve this problem?

Another question: Is possible to calculate  the hyperfine tensor with the
option 'hyperfine'?
I look at the main routine of GIPAW and i found that, authought this option
is implemented,
I did not find the subroutine hyperfine.
