Re: [Freesurfer] ROI analysis in the MNI305 space

where did aseg.nii.gz come from? Is it an individual subject or on the mni305? If from an individual try mri_vol2vol --interp nearest --mov aseg.mgz --reg transforms/talairach.xfm.lta --o aseg.mni305.mgz

To whome it may concern

I want to do a volume based analysis in the MNI305 space. Specifically i want to use the specified subcortical segments which are exteracted and labeled in the aseg.nii.gz file The problem is that the dimension of two space are not the same. How can i transform the indices of subcortical segments from aseg.nii.gz to mni305 space? Best Neda
