Dear SPMers:
I have a simple question about ROI analysis and hope you can help me.
When selecting ROI for analysis (level 2), the SPM table reports statistics
and shows the Volume and voxel sizes (at the bottom of the table). I assume
that is the ROI size. If this is correct, I found that when I selected Left
Amygdala (from WFU_PickAtlas aal) I got a Volume (no dilation) of 2880mm3
and Right Amygdala a Volume of 3848 mm3. The Right Amygdala has larger
volume than the Left Amygdala.
Is this correct?
Thanks for your help.
Lei
