Hi Freesurfers,

I am trying to use projfrac 1 to threshold my newly created cortical label to include the entire cortical ribbon since only a small number of voxels are being included in my manual tracings. My input code is: mri_vol2surf --src ./3t2234/label/15yr_lh_A1C_fs.nii.gz --out_type nifti --out ./3t2234/label/15yr_lh_A1C_new.nii.gz --regheader 3t2234 --projfrac 1 --hemi lh

I open the newly created surface with tkmedit and I get a display error (see below). Does anyone have any suggestions on how to absolve the issue?

Thanks all help appreciated,
