There is no overt spatial smoothing of the volume data in the fMRIVolume part of the functional pipeline and there is minimal 2mm FWHM surface smoothing that is done to regularize the surface in the fMRISurface part of the functional pipeline. ICA-FIX adds no smoothing.

It is preprocessed with the v3.1 functional and v3.1 ICA-FIX pipelines. I read the manual http://www.humanconnectome.org/documentation/S500/HCP_S500_Release_Reference_Manual.pdf it seems there is no spatial smoothing used for this resting state data. Hope to get a confirmation.
