Dear Stefaan and Hua
Thank you for your emails.
To respond to Hua's point about the spacegroup:
The spacegroup was 167 before we ran initso. Somehow that is not deleted by
the script which generates the new struct file taking spin-orbit interactions
into account. We deleted that manually and re-ran the calculation. It came out
with the same error at the same point.
To respond to Stefaan's point:
We agree that there could be a problem with our build of lapw2c. However we
have run the calculation on another system that has no inversion symmetry and
the calculations with spin-orbit ran through without any problem.
