Hi everyone,
Firstly - thank you for the excellent tools. This year has been my first foray into surfaced based analysis and I'm enjoying it very much.
I don't currently have a gut instinct for an appropriate level of surface smoothing. I'm sure that can't be easily answered but would a range of, say, 3 to 5mm sound good? Or more like 10 to 15mm?
Currently I'm considering cortical thickness analyses, but I may extend into functional analyses in the future.
