I think there is pretty extensive documentation of the wmparc file on
FreeSurfer’s website. I would recommend using surfaces for cortical structures.
Peace,
Matt.

Subject: [HCP-Users] the wmparc file
Dear HCP experts,
Hi. In the subject's structural folder, there is a file called "wmparc", which
seems to be the combination of the white matter and grey matter according to
fslview.
My questions are:
1. Is there any other brain structures included in this data apart from grey
and white matter, for example CSF?
2. Is there any way to separate the grey and white matter voxels, as well as
subcortical part with cortical part? We would like to acquire global white
matter voxels.
3. If used as a termination mask in fibre tracking, will this voxel mask have
the same effect as the surface mask (e.g. the pial surface)?
Look forward to your kind guidance. Thanks.
Best regards,
Xinyang
