Spintexture for the supercell in the first brillouin zone (primitive)

Dear OpenMX Community,

I am trying to calculate the spin texture for a supercell, as I am working on a heterostructure. However, I am unable to calculate it in the unfolded Brillouin zone (the first Brillouin zone of the primitive cell). The data I am obtaining corresponds to the folded Brillouin zone (the supercell Brillouin zone).

Is there any way in OpenMX to calculate the spin texture in the first Brillouin zone (primitive cell)?

I need to complete this calculation urgently. If anyone has any suggestions, I would be very grateful.

Best regards,
Aktar

Slow and steady wins the race, you know.
Follow the instruction manual.

Dear Sir,

Thank you for your prompt reply and for the helpful suggestion.

Using the link you provided, I am able to unfold the band structure and also plot the orbital-projected bands. However, I am not obtaining any spin texture information in the unfolded cell.

I would appreciate your any suggestions.

Best regards,
Aktar
