Dear PWSCF users,

When I was doing spin-orbit calculations for Ge, I got some error as
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     Error in routine tipo_sym (1):
     symmetry not recognized
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Does anyone know how to solve this problem? I don't want to use nosym =
.true., because that is too slow. Thanks.

In the following are my input varialbes
