Also, we already creaed a custom (DARTEL) GM template in SPM8 for our sample (given it is a pediatric sample) -- do you know if this is appropraite to use as the mask inpu

Since the instructions 3dFWHMx are geared towards fMRI data and suggest using the errts, it is not clear what to use to calculate smoothness estimates from
