Hi again, You pick the most probable label at each voxel. In a binary segmentation problem, that amounts to thresholding at 50%. By with more labels, it does not, eg if p(a)=p.4, p(b)=0.3 and p(c)=0.3, you pick a even though p(a)<0.5. Cheers E

Eugenio,
Yes, we are on the same page, thank you so much for the advice.
One followup question - is the threshold on the binary masks 50%?
