Hi Gergely,

it should be pretty straightforward. You need to run recon-all on all your subjects, then go through the qdec tutorial and use it to apply the simple two-class GLM.

Dear All!

First of all, I'm completely newbie to freesurfer. So far I only used FSL (mainly), rarely SPM and NordicICE.

I need to do a VBM study to compare 2 groups each containing 50 subjects for GM density (already done with FSL), volumetry (not yet done), and cortical thickness and surface area.

I'd like to do the last two with Freesurfer.

Just a single Unpaired Two-Group difference, to answer the question: Is there a significant difference between the two groups in cortical thickness or surface area.

My only problem, that I havent found any tutorials or guides (step-by-step, along with the commands) to do this.

Could anyone help me in this?

I'd really appreciate it.

Best Regards:

  Gergely Orsi
