Dear Rekha,
This is not the problem, I really write nqx1=5, nqx2=5, nqx3=3.
Any idea?
Regards,
Antoine Jay

I would like to plot the band structure obtained with HSE.
I try the trick proposed by Lorenzo: adding the K points I want to plot with weight 0 after the standard list of k points,
but I get the error "wrong EXX q grid".
Note that the first part of the list corresponds to an automatic 5 5 3 0 0 0 mesh, and that adding nqx1=5, nqx2=5, ndx3=3
CRASHs with "k + q is not an S*k"
Is it possible to overcome this issue?
