Hello, I'm wondering if surfaces need to be smoothed (and if running "recon-all -s SUBJECT -qcache" performs the smoothing) when analyzing data. Thank you. -Ryan McGarry
The -qcache option performs smoothing at 5, 10, 15, 20 and 25mm FWHM (plus 0mm, ie no smoothing). On the design tab in Qdec, there are selections for smoothing levels, and it will use the smoothed files produced by -qcache.

And just to be clearer, qcache does not actually smooth the surfaces but the thickness values on the surface. There is no need to smooth the surfaces themselves.
