* MANSEG1/2=manual segmentation, FSSEG=Freesurfer segmentation, MRIF/MRIS/PETS=structural atlas
segmentation based on FSL-MRI, SPM-MRI or SPM-PET image normalization. TRV(%)=test-retest variabilityTRV(%) of ROI volume for MANSEG2 is relative to MANSEG1. R=Pearson’s correlation coefficient (relative to
MANSEG1). SEM=standard error of measurement. Jaccard=Jaccard coefficient (relative to MANSEG1).
