Hi Sahil
can you clarify what you mean. Do you have the left hemi SMA labeled in MNI space and it (incorrectly) extends into the right hemi? Or are you trying to draw both the left and the right SMA?

Hi everyone, I have supplementary motor area (SMA) defined in standard MNI volume space and I would like to extract cortical thickness for this area. I have 80% of SMA in left hemisphere and 20% on right hemisphere. So I am stuck at the command mri_vol2surf before proceeding to mri_segstats.
In mri_vol2surf, I am not sure what should I specify for --hemi i.e. whether its left or right hemisphere (lh or rh). If I specify e.g. lh, then would not it convert left hemisphere SMA voxels to surface and later on extract the measure from left hemisphere only and vice-versa for right hemisphere.
I am not sure how would that work if portion of ROI is on both hemispheres and how can I run mri_vol2surf command?
Thanks, Sahil
