Dear Veronique, the [-r] option is not much tested (if tested at all). The main reason is that typical supercells with disorder have a low symmetry. I do not exclude that some supercells can possess the inversion, but I did not have such before in practice. Would you mind sharing a simplest struct file of your supercell with inversion?
As a temporary solution, one can break the inversion symmetry with labels (e.g., Sr1, Sr2, ...). This will force the complex calculation.

I've tried it for the very simple FeSe (attached case), trying to unfold with 2:2:1, but also for Sr2IrO4 or SrIrO3 (the case I'm interested in at the moment, also attached) or your examples. Everything works fine in complex mode, but not with another switch. For example both FeSe and SrIrO3 have inversion symmetry and do not require complex calculation, but if I run the case in real mode, fold2Bloch recognizes well it's a real case.vector (it asks for the -r switch), but cannot process it (segmentation error).
