Those are some big segs. Have you checked the registration?

yes :) For example in this 1 subject segs ( 2005 2008 2010 2011 2013 2021 2023 2025 2029 1005 1008 1011 1013 1021) are all missing..
The missing segs are not consistent across subjs(i.e. other subjs have different segs missing). I chose a list of 86 segs to 'cover' the brain and not sure if I was over-reaching..Also some segs are reading with value 100 (i.e. all voxels have a value of 100)?

there were probably some small segmentations that were lost. Is this causing a problem? On 11/19/2013 02:22 PM, Sudhin A. Shah wrote:
Hello,
This is regarding the registration of functional data to freesurfer parcellations (http://freesurfer.net/fswiki/FsTutorial/MapSegmentationsToFunctionalSpace).
The rsfMRI is sampled at 2x2x2.
After running reg-feat2anat and aseg2feat
a = MRIread('aparc+aseg'); %Original aparc+aseg output from
freesurfer recon-all
size(unique(a.vol(:))) % 114 segs a = MRIread('aparc+aseg'); % this is the output file after aseg2feat size(unique(a.vol(:))) % 98 segs
Any advice?
Thanks
