Hello,

You mean the group analysis? we have a lot of choice, in Freesurfer, you can use Qdec or command line, but actually, here, I just do some regression in one group, so it is not really two groups, then I just wanna plot the p value for the correlation into the anatomical image.


For your question, you can use matlab regression function, FS group analysis, or surfstat, you have a lot of choices, but anyway, they are the same.


I will give you some links here:

Hey Hao,
What software did you use to do your analysis? Also, if you are ok with it, can you please post your scripts on how you did it. I want to implement it in my analysis. Thank you very much.

Hello:

I have a question, after recon-all, I did some group analysis with the aseg.stats( not surface-based), so my question is :

Does freesurfer has some volume-based group analysis(not for fMRI) for plotting the significance map, I searched google, and wanna some results like this:

I know here is for fMRI-sMRI based analysis:


So i want to map some values for the subcortical structures in the anatomical image, but for the command here, how can I get the sig.nii(right now, we just have the result p-value for every subcortical structures), I know in FS, we can use mri_glmfit to have the significance map


Any advice will be appreciated


Hao
