[Wien] XMCD S K-edge

Dear Prof. Peter Blaha and Yongbin,

I have already successfully calculated XMCD spectra for the U M45 edges.
I got into trouble for the S K-edge computation.

When I checked the case.symmat1up file I got NAN values. Here is the detail
of the file













*    T   K       LEFT        RIGHT         ALL   KP:     1 NEMIN NEMAX :
  1   54 dE:*****10.00 K:         1    1s    1          NaN          NaN
1s    2          NaN          NaN    1s    3          NaN          NaN
1s    4          NaN          NaN    1s    5          NaN          NaN
1s    6          NaN          NaN   .   .   .*

I am not sure what went wrong here. For all the K-points I am getting the
same like the above.
The case.inop file is given below:


















*99999 1       number of k-points, first k-point -25.0 10.0 9999 Emin, Emax
for matrix elements, NBvalMAXXMCD 1 K      optional line: for XMCD of 1st
atom and Kedge spectrum2             number of choices (columns in
*outmat): 2: hex or tetrag. case1             Re xx3             Re zzOFF
        ON/OFF   writes MME to unit 4Choices:1......Re <x><x>2......Re
<y><y>3......Re <z><z>4......Re <x><y>5......Re <x><z>6......Re

How can I fix this? Could you help me?

Thank you.
