[CP2K-user] [CP2K:13155] Kpoint symmetry true with spglib

[hut... at chem.uzh.ch]

Hi

this feature is not implemented. A symmetry reduced k-point grid
cannot be used.

regards

Subject: [CP2K:13155] Kpoint symmetry true with spglib

Dear CP2K developers and users,

I would like to know how to perform a period calculation with symmetry true inside the kpoints input block in order to reduce the numbers of Kpoints in the reciprocal space
I compiled CP2K linking several libraries including spglib version 1.9.9 but when I run a simple optimization of a periodic system with the following computational setup the program stops whit this message:

 here you have the keywords used inside the kpoints block
    &KPOINTS
      SCHEME MONKHORST-PACK 6 6 6
      SYMMETRY .TRUE.
      VERBOSE .TRUE.
    &END KPOINTS


Probably I am missing something...
Could you please explain me how to fix this issue?
Thanks in advance
lorenzo
