Hi, Lorenzo
It complaint in the output "noncollinear stress +GGA in not implemented". What
should I do next if I insist on using spin orbital coupling ?

I think that stress is not computed when using spin orbit coupling with PAW
datasets, it shouldn be stated in output anyway, I recommend you check.

Dear QE community,
I am performing vc-relax calculations using QE-6.4.1. However, it seems that
vc-relax does not take effect at all; the unit cell is frozen at the size
of beginning. Please help me.
