[Wien] Spin-orbit calculation error in lapw2

Dear Wien users,

I am doing a spin-polarised calculation including spin-orbit for a system
which has inversion symmetry. The calculation without spin-orbit runs through
without any problem.When I include spin-orbit, the programme crashes out of
lapw2c with the error message given at the end of this mail. When I looked at
the uplapw2.def file I find that it needs the case.in1c file. However since
the system has inversion symmetry the real version of lapw1 is accessed. I
tried to copy the case.in1 file into case.in1c but that did not solve the problem.

I also attach the struct file. Could someone tell me where I am going wrong?
For the spin-orbit calculation I use

runsp_lapw -so

Thanks in advance for your help.

Best wishes,

Priya
