Dear pwscf users,

When I perform relaxing calculation (calculation ='relax' and ion_dynamics ='bfgs'), I encounter a problem related to symmetry. The error information is as following. But the scf calculation is OK. My system is a spinel structure (F-3dm).
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  from checkallsym error #   2
  symmetry operation not satisfied
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

How to solve this problem? I would appreciate your help.

Best regards,
Chaohao
