Dear all,

I've already downloaded the ATAG atlas from 'http://www.nitrc.org/projects/atag'. I want to extract the specified ROI according to a defined probabilistic value. However, when I look at the probabilistic values in voxels in each ATAG atlas, they are larger than 1.  what the value in each voxel in ATAG atlas represents?  



Thanks for your help with this,
Yongqin
