For instance, if there is any way to extract spatial location of cluster X1 and use this location to extract thickness values of all the subjects from P2 and P3, that way I can perform two-sample t-test. I am not sure if that's feasible and if so, then how can we do that?

Hi experts,

I found a cluster X1, which showed significant difference in cortical thickness between two groups C1 and P1, determined using mris_preproc, mri_surf2surf and mri_glmfit commands.

I am interested in determining if the same cluster X1 has significantly different cortical thickness group between two other groups P2 and P3.

I would really appreciate if you could please give me the step-by-step guidance how this can be done.

Thanks.
