Re: [Freesurfer] smoothing data
Smoothing in the volume is the single worst thing that is traditionally done to brain imaging data as far as precision of spatial localization goes. Peace, Matt.

Re: [Freesurfer] smoothing data
you should definitely not smooth the volume data. Smoothing should be limited to the surface.

[Freesurfer] smoothing data
Hi All, I was hoping someone can help me with two naive questions I have: I have read on the Freesufer wiki that you should smooth surface data before analyzing. Should I smooth the data only after I have ran recon-all and have made edits? Also, should volumetric data be smoothed or is this limited to surface data? Thank you in advance for your help.
