Thanks for bringing this issue up. I made modifications to the MATLAB
script that plots the unfolded band structure. It contains now a variable
FOLDS = [1 2 3] that represents an arbitrary multiplicity selected when
constructing a supercell. The updated script is located at
https://github.com/rubel75/fold2Bloch/tree/master/Utils

I hope it will work for you.

Thank you
Oleg
