Re: [HCP-Users] Freesurfer total intracranial volume

[Harms, Michael]

No.  eTIV is entirely dependent on the accuracy of the Talairach transform, and we didn’t QC the Talairach transform.  (We QC the surfaces themselves, but not the Talairach transform, since the surfaces can be fine, even when the Talairach transform isn’t accurate).  So, we didn’t include that TIV value in the data dictionary/spreadsheet.  There are other measures available if you just want a measure of total brain volume. cheers, -MH   --  Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO  63110 Email: mha...@wustl.edu From: <hcp-users-boun...@humanconnectome.org> on behalf of Chao Zhang <cha...@gmail.com> Date: Monday, May 23, 2016 at 11:17 AM To: "hcp-users@humanconnectome.org" <hcp-users@humanconnectome.org> Subject: [HCP-Users] Freesurfer total intracranial volume Hi I wonder if the total intracranial volume (TIV) information from the freesurfer pipeline is available? I did not find it in the data dictionary and the spreadsheet.  Best, Chao _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users   The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.
