Hi,
I have a question about citation for smoothing methods.
In the following link,
http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/FslFeatFreeSurfer
there are statement " ....This data was smoothed in the volume at 5mm, but when preparing for a group surface-based analysis, we recommend that you smooth on the surface prior to group analysis and not smooth in the volume at all (or less than the voxel size) ...."
Is there any reference paper that I can cite when I write a manuscript?
thank you very much.
