[Freesurfer] Hippocampal Subfields Posterior Probability

Hello Dr. Iglesias,

I'm currently examining the distributions of the posterior probabilities of the different hippocampal subfields, and I'm interested in obtaining the probability distribution images for the subfields that correspond to the volumes output in the subjects text file.

While I can use mri_binarize on ?h.hippoSfLabels-T1.v10.mgz to obtain the subfield masks and use them to obtain the posterior probabilities distribution after soft segmentation,

is there some other straighforward way to obtain these posterior probabilities for the volumes stated in the output text file ?

A follow up question - It appears that the soft segmentation approach approximates thresholding the posteriors by a value around 0.5 ? In your opinion, is this value acceptable and have you found similar values in your testing ?

Thanks!
