[CP2K-user] crystal symmetry

Hello,

Is it possible to constrain the crystal symmetry during GEO_OPT?
Should the relaxation be constrained by the group symmetry?
I'm relaxing the excited state structure of bulk crystals using ROKS. 
But I obtained many stable states within the bandgap. I guess the 
relaxation should conserve the group symmetry of the crystal and some
of the relaxed states should be abandoned due to symmetry reason.

Best,
Xiaoming
