[Pw_forum] tetrahedra error

Thanks for the recent advice on the Constrained VC relaxation

On a different subject:

I am trying out the procedure for calculating density of states (using
dos.x). I am trying to do it for Cobalt.

I have run the scf calculation successfully. When I do the next stage (as in
example08), I get the following error message:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from tetrahedra : error #        13
     cannot remap grid on k-point list
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I'm not sure what the problem is.

Here is my input:

&CONTROL
