Table 1. Overlap of Significant Cluster Produce by Different Motion Corrections.

SPM and FSL columns represent each software packages standard motion correction algorithm with default parameters. The n, n-½ and n-1 columns represent the presented motion correction algorithm using frame n, n-½, and n-1 to correct for the motion in frame n. Please note the dramatic (and statistically significant deterioration) between the two approach that do not add delay to the system, our proposed n-½ approach and the commonly used n-1 approach.

	FSL	N	N-½	N-1
SPM	80.20	81.68	78.95	69.07
FSL		80.35	78.76	68.69
N			87.96	75.29
N-½				76.05
