Whitening is done by default (you can turn it off with -nowhiten to mkanalysis-sess). It uses an AR1 model.

Hello Freesurfer Experts,
May I ask if there is a whitening/weighting matrix used to give weighted least squares estimates (WLS) and whiten the data during the 1st-level model estimation in FSFAST? If so, how could I get it?
Many thanks and kind regards,
Lizhi
