Hi, The number of vertices on the surface is of the order of ~60k (excluding subcortical regions). I wish to work in an ROI space (say 100 ROIs) by clustering the cortical vertices that are near-by. To do so, I need to know the co-ordinates of the vertices on the surface. I had the following questions regarding this:
1. Does the data in *.dtseries.nii correspond to the time series of the vertices after surface alignment? If so, which is the file containing the coordinates of these vertices? 2. Do the vertices across patients correspond to the same region in the brain? If this is true, shouldn't there be one surface file for all subjects after alignment? I'm wondering why there's a surface file for each subject. Thank you in advance. Sincerely, Manasij _______________________________________________ HCP-Users mailing list HCP-Users@humanconnectome.org http://lists.humanconnectome.org/mailman/listinfo/hcp-users
