Re: [Freesurfer] roi mask?

Hi Bruce,

Thanks for the fast response! I indeed found them in other stats files. What is the difference between these files? I assume they are based on different atlases? I saw that there are some slight differences between the numbers in different files for the same structures, so how do I know which file I should use?

Thank you so much for your help!

Best,

Marja

it depends what they are. You can look in the other stats files to see if they are there (we include a couple of cortical parcellations). If they aren't, you can draw them yourself on fsaverage and map them to all your subjects using our spherical transform

Hi Bruce,

Thanks, that indeed includes most of the roi's I want to include. What if there are some area's that are not in that list? Is there a way of adding areas?

Best,

  what ROI do you mean? We generate lots of them, and tabulate the
  thickness within each one. Look for example in <subject
  id>/stats/aparc.stats

        Hi all,

        So I ran a recon-all -all on one of my subjects, and
        it completed without
        errors (according to the log). Now I would like to
        get cortical thickness
        numbers from this subject, but when I open the
        tutorial regarding this, it
        says it assumes that you already have a roi mask and
        a T1 in the same
        coordinate space as the roi mask.

        Did the recon -all -all by any chance create these
        files? And if not, how
        can I?

        So basically the question is; what do I have to do
        after recon -all -all in
        order to get cortical thickness numbers in roi's of
        my subjects?

        Thanks in advance.

        Marja
