Dear all,

I am running a structural optimization with QE 6.0. The structure is 
orthorhombic, ibrav=8, with 8 symmetry elements. The first run did not converge 
so I have to restart it. But as I restart it, the number of symmetry is now 4, 
there is a descent of symmetry. I shall say that I use the space_group option 
with COORDINATES crystal_sg. But the problem remains if I put all the 
coordinates (unsurprisingly).

Is there a reason for this, and can I avoid this?

Thank you
Best regards
Pascal
