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
