Dear surfers,
I want to ask whether it is possible to have a tissue probability map of the brain according to aseg.mgz. If I am not wrong aseg.mgz is the MAP estimate of a Markov Random Field based segmentation hence we shall get the probability maps for each label or tissue. Is it possible? Best,
Burak
Hi Burak,
I think if you give mri_ca_label the cmdline option -write_probs <name>
it will write out the label p values at each iteration of the ICM alorithm. Note that these are not real probabilities, but monotonically related to them. It's also pretty old code that I wrote for debugging and haven't looked at in years. Hopefully it still works :)
cheers, Bruce
