Hello,

I have downloaded the AAL atlas, and resliced the atlas to voxel size 4x4x4. I noticed that there were 116 ROIs. The mean ROI size is 200, and the Std. Dev. ROI Size is 145, which are different from the numbers shown in the Table "ROI Atlas Comparison" on page http://www.nitrc.org/plugins/mwiki/index...

Could anybody tell me what's going on? Did I do something wrong?

Thanks
