I have some MRI images from a GE scanner, it seems that images’ quality is poor because grey matter is bright in so much area and these grey matter is included in wm.mgz. So I deleted wrong voxels in wm.mgz by freeview and rerun through command “ recon-all -autorecon2-wm -autorecon3 -subjid subjname”. But ?h.white (yellow line) don’t change after rerunning as you can see in the attached picture. Is this problem caused by deleting too many voxels and how to fix it? Thanks very much.
