Hi Reddy,
the nu isn't smoothing them, it's what we call the "conform" process -
interpolating to 1mm isotropic. Your voxels are 1.25x1.25x1.2, which is
almost 90% larger than 1mm iso, so when we upsample them there is a bunch
of interpolation.
cheers

Hi Bruce,
I got a problem with mri_nu_correct in recon-all process. After mri_nu_corret
step, nu.mgz looks oversmoothed. Could you please let me know why this is
happening and how can I get rid of this?
This is happening with few images only. I attached original (001.mgz), nu
corrected (nu.mgz) images and mri_nu_correct.mni.log file for your reference.
Thanks in advance!
Reddy.
