Hello experts, 

I am trying to convert insula ROIs that are in MNI 152 2 mm space to MNI305 space. I will eventually this ROI for connectivity analysis. 

I ran mri_vol2vol: 

mri_vol2vol --mov $FREESURFER_HOME/subjects/fsaverage/mri/orig.mgz --targ /autofs/cluster/neuromod/Insula_ROIs/left/k10/cluster_1.nii.gz --reg $FREESURFER_HOME/subjects/fsaverage/mri.2mm/reg.2mm.mni152.dat --inv --o cluster_1.mni305.mgz

When I visualize the results the converted ROI is more caudal than the original. What am I doing wrong?
