Neither of these two bits of advice is correct:

1. q_in_band_form can be used with ibrav=0 as usual, and works just as 
well as long as you specify the point coordinates
2. there is no specific reason to use crystal coordinates with ibrav=0, 
you can, as usual, but by no mean you "need to"


kind regards
