Re: [Freesurfer] multiple comparisons correction for individual hemispheres (native space)

Dear Doug, I tried to run MCC with cluster-sess but unfortunately I got the same error message like when I'm using mri_glmfit-sim. It does not recognize the thresh (cluster-forming thresh) Here is the terminal output: Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME /h

[Freesurfer] Probabilities in the Brodmann area labels

Dear FreeSurfer Experts, I am puzzeled about the probabilities in the Brodmann area labels. If I take the Brodmann areas 1, 2, 3a and 3b and add their probabilities at a certain vertex a probability sum < 1 should arise. This is due to the fact that 10 brains where analyzed in order to compute

the thickness you can generate using mris_thikness. Why do you want to generate a wm.mgz? I guess you could from the wmparc On Mon, 8 Dec 2014, Xiaomin Yue wrote: Hi All,   Cortical surface reconstructed using caret from a high resolution MRI data (0.25 mm) has been converted to freesurfe

Hi Bruce, Thanks for your response. What's the inputs to the mris_thickness? I need the wm.mgz to generate the ratio of gray vs. white matter. Xiaomin Date: Tue, 9 Dec 2014 09:55:21 -0500 From: fis...@nmr.mgh.harvard.edu To: freesurfer@nmr.mgh.harvard.edu Subject: Re: [Freesurfer] thickness

[Freesurfer] Modeling cortical thickness question

Hello Freesurfers, Our group is wondering if any of you know whether it is possible to model cortical thickness as a third order polynomial? The specific question is: we are looking at whether there is a hyperbolic relationship between cortical thickness and date of birth among a cohort of individ

[Freesurfer] Problem with mris_register: face not in vertex face list

Dear Freesurfer support community, I am having a recurring issue with re-running a participant after making manual white matter edits (i.e., filling in holes in the wm.mgz file). I saved the new wm.mgz file and then reran using -make all (twice). For some reason, Freesurfer stops at the Surf Re

Re: [Freesurfer] thickness from pial and white

it creates a file in curvature format, yes. Did you try mris_fill for the wm.mgz? It won't be exactly the same as the one we would generate. You could use mris_fill to generate the interior of the ?h.white surface, then use the aseg to remove non-wm voxels I guess On Tue, 9 Dec 2014, Xiaomin Yu
