Dear Li,
the only idea I have what caused these deviating results is that you have probably not used absolute thresholds during statistical analysis.
Best,

>When I use CAT12.8 to do ROI analysis of cerebellum of longitudinal data using suit or lpba atalas, I found that cerebellar gray matter decreased much more than voxel result, but cerebellar white matter elevated, while cerebellar white matter of voxel result showed decreased. This is very strange, I thought maybe some cerebellar gray matter misclassfied into white matter, so total volume is more suitable in ROI analysis?Thank you very much
