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,

you should definitely not smooth the volume data. Smoothing should be limited to the surface.

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.

Best, Tamara
