1.How do I register subjects’ thickness maps to a common space to be able to do vertex wise comparison? And can any brain map be used as the common space?
This is the same as doing a group analysis. Basically you run mris_preproc, mris_fwhm to smooth, then mri_glmfit to do the comparison. Look at the group analysis tutorial. We define a surface-based common space for group analysis, but you can also make your own.
2.If I have a hand-drawn ROI on subject’s original T1, is it possible to resample the volume ROI to the surface (so I can extract the thickness values from that ROI)
Yes. You can run mri_vol2surf to sample the binary ROI onto the surface, then mri_cor2label to create a label.
Any command lines would be appreciated.
Best,
Tony
