Hi, thanks for help. That was the segmentation i was looking for. Now the question is what is the look up table Freesurfer uses to assign values to different labels? in other words, if I want to segment the "G_postcentral" (for e.g.) what value should i look for? bets

Have you looked at the aparc+aseg.mgz? It has cortical and subcortical labelings. You can convert it to analyze with mri_convert.

Hi,
I actually had the some extra question in addition to the question Shahab had. So i thought to put the questions in the reply. My final goal is to have Cortical Regions segmented at the subjects native coordinate space. And I prefer to have the segmentation in analyze format.
and also, I was wondering if 1- there is a way of saving Surfaces generated with FreeSurfer into an analyze image. 2- If we can control how fine the cortical segmentation be. (the number of regions segmented).
Behrang,

Hi Shahab,
the ?h.*.annot files are the cortical labelings. What exactly do you wat to do with them?

Hi,
I can extract subcorical objects from freesurfer segmentation, since
each object is lableled with normalized intesity value. I was wondering if I can extract different cortical regions in the same fashion. I can, though, view the labeled cotical surface in tksurfer.
Thanks Shahab
