I ran a surface based pet analysis and I found 6 surviving clusters in the cluster-wise map. However, when I tried to view the voxel-wise map ( mc-z.abs.13.sig.voxel.mgh), it displayed as yellow meaning there was nothing (see attached). Shouldn't it be showing regions that survived at voxel-wise level?  Any ideas why it isn't displaying the appropriate figure? 

Also, what does the content of this file (mc-z.abs.13.sig.voxel.max.dat) mean? 

Thank you. 

Best,

Paul
