Symmetry not recognized by TURBOMOLE

TURBOMOLE calculations with c<n> symmetrical molecules do not recognize correct symmetry during setup of the calculation.

• When starting the calculation via cefine (define), the following error message results:

 MOs are in ASCII format !

• When starting the calculation via a control file setup (without $symmetry block), c1 is assumed.
  Example for control file:

$coord file=coord
$charge=0 unpaired=0
$atoms
   basis=def2-SVP
$dft
   functional PBE
   gridsize m4
$rij
$disp4
$scfiterlimit 100
$scfconv 7
$energy file=energy
$grad file=gradient
$end

Still happens sometimes with the same error:

 No input with occupation numbers/open-shell information found

 start vectors will be provided by an EHT guess

 The EHT guess will be determined for:
   molecular charge   :    0
   number of electrons:  255
   S_z eigenvalue     :    1
  missing alpha occupation number declaration 
  missing beta occupation number declaration
