Hi Freesurfer experts,

I have a volume label only which is only different from zero in the 
white matter-gray matter boundary. I am trying to convert this volume 
label to a surface label in order to visualize it in tksurfer. I am 
using mri_vol2surf:

mri_vol2surf --mov volume_label.nii --out volume_label2surf.mgh 
--out_type mgh --hemi lh --regheader H01 --surf white --ref volume_label.nii

However, when I load this surface as an overlay in tksurfer, to check 
the correctness, the original surface is not fully covered by the 
surface created by mri_vol2surf. Is there any way to make the surface 
fully cover the original surface so it doesn't look speckled?

After creating the surface I want to convert the surface to labels by 
mri_cor2label and finally to an annotation file by mris_label2annot.

Best,
Karen
