Before revision:  Though temporal autocorrelation modeling in AFNI was not perfect, its performance was much higher than the performance of temporal autocorrelation modeling in FSL and SPM.  FSL and SPM could improve their autocorrelation modeling approaches for example by adopting a noise modelsimilar to the one used by AFNI .
After revision:  Though temporal autocorrelation modeling in AFNI was not perfect, its performance was much higher than the performance of temporal autocorrelation modeling in FSL and SPM. The residual autocorrelated noise in FSL and SPM could improve their autocorrelation modeling approaches for example by adopting a noise modelsimilar to the one used by AFNI .
