Hi Pedro,

So lGI is inherently very smoothed, and you don’t want to over smooth (which is why you get this error), so I usually recommend either no smoothing (fwhm=0) or fwhm=5mm, given that these are the options easily inputed in qdec. I’d say try first with 5mm, and check if this work, if it doesn't decrease to 0mm. And if you want then to work around, you can tune your smoothing with values in between to achieve a smoothness level of 15mm, most often with 1 or 2mm, but qdec won’t accept it so you’ll have to go for the commandline stats.

Hope it helps,

Marie
