External Email - Use Caution        

Dear all,

How can I run a voxelwise statistic using grey and white matter uptake? mgx.ctxgm.nii.gz and the other files in output all only include gm as I understand. 

My goal is to run whole brain volume-based analysis. Like in this example for subcortical analysis:

mri_vol2vol --mov subctxgm.nii.gz --reg aux/bbpet2anat.lta
--tal --talres 2  --o subctxgm.mni305.2mm.sm00.nii.gz

Thanks, 
Boris
