Dear nicola,
Thank you so much for your reply. But I don't understand.
According to wikipedia's picture, the only Γ - K - X path that I can see is like this
I can not see any other possibility. Would you please show me what is the other possible path for Γ - K - X in a picture? Thank you so much.
And I do the phonon dispersion calculation using q_in_band_form for matdyn.x, k path labels are default. I thought this is standard.
best regards
