To reinforce what bruce is saying, mri_surf2surf does surface-based smoothing (ie, along the cortical surface), whereas fslmaths does volume-based smoothing which does not take into account the anatomy On 12/12/2017 10:38 AM, Bruce Fischl wrote: > Hi John > > I don't think fslmaths takes a surf

Hi John I don't think fslmaths takes a surface topology so they won't be the same (mri_surf2surf smooths within the surface and fslmaths smooths in the volume I believe) cheers Bruce On Tue, 12 Dec 2017, John Anderson wrote: Dear Freesurfer experts, I ran recon-all with the flag -qcache t

Dear Freesurfer experts, I ran recon-all with the flag -qcache to generate smoothed cortical thickness maps. In order to check how the flag "-qcache" is smoothing the cortical thickness data. I looked into the file $subj_dir/scripts/recon-all.log" which showed that the following command was appl
