Thanks. And can you also check which freesurfer build you're using? Look for the line that says "build-stamp" towards the beginning of your trac-all.log file.

Re: [Freesurfer] Problems with LME-Setup
by Vivian R. Steiger 02 Oct '13

Hi Jorge Thank you for your answer our question about CM. I worked so far and the results are in line with glm_fit as you predicted. If we would like to compare the groups (4th column in our qdec.table, with (responder = 1), (non-responder = 2) coded) the CM.C would be [0 0 1 0] ? We have unbalanced group sizes here 14 responder vs. 9 non-responder. Thanks for your assistance Best, Vivian

overlay mni152 activation -- difference between tksurfer and freeview
by Yang, Daniel 01 Oct '13

01 Oct '13

Dear FreeSurfer Experts, I am trying to visualize fMRI activation (generated from fsl) on the fsaverage inflated surface, using mni152.register.dat. It's odd that I find the results to be slightly different between tksurfer and freeview. However, I made sure that I am using the same threshold... Judging from fslview, I think the result with freeview is more accurate -- is it due to tksurfer loading orig.mgz by default, and free view loading something else? Thanks!

Hi Freesurfers, I just looked at my cortical thickness results, in which I performed an interaction between group (2 groups) and cognition (continuous). I see regions popping up, which is great! Especially since they are related to the task. Now, I made a scatterplot of some of these vertices to get a better understanding of the effect. However, I am wondering how I can figure out if the slope within each group is significant. How can I examine that? Thanks!

Dear FS experts, I want to perform asymmetry study in a group of subjects. I have created myatlas.i3 from my data(86) based on the procedure from Xhemi page and tksurfer lh inflated of both fsaverage and myatlas image is attached! it has shown that my atlas is smaller in general and larger in temporal lobe! I wonder if this is correct and I can proceed to compare left and right Hemispheres? -- Best regards, Amirhossein Manzouri
