Hi Tom, Why not use the multi-modal parcellation? https://balsa.wustl.edu/file/show/3VLx

We're using it to just coarsely chop up the surface to build phenotypes. What atlas would you suggest that we can easily apply with wb_command -cifti-parcellate? -Tom On Mon, Jun 4, 2018 at 4:29 PM, Glasser, Matthew <[email protected]<mailto:[email protected]>> wrote: Hi Tom, This is because FreeSurfer “fits” the aparc to each subject. There is probably an atlas aparc somewhere inside FreeSurfer that wouldn’t have this property. That does raise the question of why you are using aparc instead of one of the more functionally relevant parcellations available in standard CIFTI space though. Aparc is unlikely to follow task boundaries much at all. Matt.

We're using the aparc segmentations to extract data from the task fMRI CIFTI files. We believe that we're working in atlas space (32k_fs_LR), so we were surprised that, when we load two different subjects into wb_view, the aparc segmentations are different for different subjects. See attached images of 100206.aparc.32k_fs_LR.dlabel.nii & 100307.aparc.32k_fs_LR.dlabel.nii The regions are similar but differ slightly, with the white dot showing a particular bit of the surface that changes from one ROI to another between subjects. I would have expected this if we were in native space, but not 32k_fs_LR. What am I missing? Thanks in advance! -Tom PS: A similar question was asked on May 9, titled "about the D-K atlas" from [email protected]<mailto:[email protected]> but it hasn't been answered; oddly, while it is in my inbox I can't find it in the archive. __________________________________________________________ Thomas Nichols, PhD Professor of Neuroimaging Statistics Nuffield Department of Population Health | University of Oxford Big Data Institute | Li Ka Shing Centre for Health Information and Discovery Old Road Campus | Headington | Oxford | OX3 7LF | United Kingdom T: +44 1865 743590 | E: [email protected]<mailto:[email protected]> W: http://nisox.org | http://www.bdi.ox.ac.uk _______________________________________________ HCP-Users mailing list [email protected]<mailto:[email protected]> http://lists.humanconnectome.org/mailman/listinfo/hcp-users -- __________________________________________________________ Thomas Nichols, PhD Professor of Neuroimaging Statistics Nuffield Department of Population Health | University of Oxford Big Data Institute | Li Ka Shing Centre for Health Information and Discovery Old Road Campus | Headington | Oxford | OX3 7LF | United Kingdom T: +44 1865 743590 | E: [email protected]<mailto:[email protected]> W: http://nisox.org | http://www.bdi.ox.ac.uk _______________________________________________ HCP-Users mailing list [email protected] http://lists.humanconnectome.org/mailman/listinfo/hcp-users
