Hi Douglas,

I have done this and I got the following message:

“cd /data/PDE10_PD_DENOVO/Freesurfer/DENOVO/subjects/PD1/mri
hwilson@nig05 mri]$   mri_nu_correct.mni --n 1 --proto-iters 1000 --distance 50 --no-rescale 
ERROR: must specify an input volume
hwilson@nig05 mri]$ --i orig.mgz --o orig_nu.mgz “


Many Thanks

With Best Wishes

Flavia
