Perhaps it smooths the data some and that would impair the gradient placement
of the final white and pial surfaces?

Subject: [Freesurfer] use of ANTs Denoising in FS 7.1
External Email - Use Caution
Hi all,
In previous datasets, and prior to FS 7, we independently ran ANTs denosing on
the input T1s prior to running recon-all,
However, FS 7.1 now appears to use the denosing utility in parts of the
pipeline.
“ANTS denoise is used when creating the orig surface (but not thefinal
surfaces)”
Does this mean the denoised image is only used in the segmentation part of the
pipeline (to generated the aseg.mgz) and does not propagate through to final
surfaces? Why not use denoised T1 through the surface-generation phase of the
pipeline.
Can you provide some further clarification.
Thx.
Jim
