Re: [Freesurfer] smoothing data

2017-07-12 Thread Matt Glasser
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.

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

[Freesurfer] smoothing data

2017-07-10 Thread Tamara Tavares
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
