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
