about kptopt variable

Hi, everyone, I got a new question. I found when generating k points, the time reversal symmetry is turned on, how to switch it off so that the k points (non-symmetric) generated would not consist the (-k) elements. I have already tried on kptopt to be 4 according to the instruction, but abinit repo...

Contour deformation kpoints in graphene calc

Hi, I am recently recalculating the classic paper applying GW on graphene ( PhysRevLett.101.226405 ). They mentioned that convergence was made at 10by10by1 kpoint grid and they calcluated the GW bandstructure at K(0.333 0.333 0) and a point near K (0.328). But I read in the tutorial that the calcula...
