It will affect it some because the tessellations will be different. I have not done too many experiments to measure it, but the one I did do showed very little difference when using a subject-specific atlas. Your mileage may vary. mri_glmfit-sim expects there to be tables for each atlas. > > 2) I downloaded the simulations for multiple comparisons correction > mult-comp_cor.tar.gz.
