Hey Rick,
We have a quick questions about calling detrend in 3dFWHMx.
First, since afni_proc already detrends we figured the residuals would already be detrended. Would you expect running detrend with 3dFWHMx on residuals to have considerable impact since they should have already been detrended by afni_proc.
Second, since afni_proc detrends for each run could some of the differences we are seeing be explained by the fact that when we estimate the blur from the residuals its is the full concatenate set of runs and not the individual runs themselves?
Thanks
Steve
