External Email - Use Caution Hi Freesurfer experts,
Follow up on the last question and correct me if I am wrong, the difference between dlabel/diff/lowb_brain_mask.nii.gz and dmri/nodif_brain_mask.nii.gz is that: > the dlabel/diff/lowb_brain_mask.nii.gz is generated from "bet" (brain extraction) > and dmri/nodif_brain_mask.nii is derived from aparc+aseg_mask.nii.gz which contains T1 information. Because in fsl, nodif_brain_mask is named for "bet binary brain mask".
