No. You could it in matlab by setting all of the left (or right) segments to 0, eg, a = MRIread('aseg.mgz'); ind = find(a.vol == 17); % Left hippo a.vol(ind) = 0; % Set all left hippo to 0 and so on for the other segments On 12/26/17 12:24 AM, Fereshte wrote: Dear Experts, I'd appreciate y

In theory it is because the F can be converted to a p which can be converted into a pseudo-z. When you run mri_glmfit-sim, you should make sure to use an unsigned test ("abs") On 12/22/17 8:08 PM, basile pinsard wrote: Hi Freesurfer experts. Does mri_glmfit-sim Monte-Carlo cluster size correc

It is appropriate. The F-test is not the same as t-test, so it is not totally surpising that you get different results On 12/22/17 5:06 PM, Pauline Duret wrote: Hello all, I am running a gyrification analysis between 3 groups. So I modeled my GLM like the one on this page: https://surfer.nmr

Probably not because of the voxel size. First, check the registration. If it looks ok, then you can re-run with -no-talcheck. If it does, not look good, then fix it and rerun. On 12/28/17 6:15 PM, 박경일 wrote: Dear experts, I am sorry for asking again. I have some problems in running recon-all
