The autocorrelation function is computed at each voxel from the 
residual, these are fit to an AR1 model and adjusted for residual bias. 
They are spatially clustered based on AR1 value. The Sn is computed as a 
toeplitz matrix of the autocorrelation function derived from the 
best-fit AR1 model (that matrix is multipled by the residual variance to 
get the final Sn).

It is really nothing fancy, just down-weighting each subject by the 
residual standard deviation.
