Re: [Freesurfer] Q) Medial_wall.label

Hi Yune

you are better off using the ?h.cortex.label file to mask in what is needed for each subject

Hello freesurfer experts,  For visualization purpose (i.e., displaying group maps), I applied a mask for medial wall regions using the files (e.g., rh.Medial_wall.label or lh.Medial.wall.label), which I found in fsaverage/label/ directory.

However, I noticed a somewhat imperfect medial wall masking in both hemispheres, such that  transversing lines are seen in unthresholded t maps for both hemispheres (see attached ).

Those lines eventually disappear when I increased threshold, but I wonder why this happened.

Any ideas?

best, yune
