Dear Eugenio,
/"assign to each voxel the label with the highest posterior probability"
/implies that each voxel must belong to *one and only one* label, right?
I've found that this is not the case with the posterior_*.mgz files
outputted by freesurfer, where each voxel (especially the ones with the
lower prob values) can belong to multiple labels.
The passages I've done to come up at this conclusion was:
1) binarize all the posterior maps
2) summing them up
3) search for values greater than 1
4) if there are values >1, then there are voxels belonging to multiple
labels.
I've found voxels belonging to 7 different labels at the same time!
I think that the posterior files outputted by freesurfer are missing the
final step of required to each voxel to the *single* label with the
highest posterior prob.
I think that a clarification from the developers is needed here.
Best regards,
Luigi.
