: Comparison of motion correction and distortion correction (MCDC) between FEAT and dHCP pipelines using t-statistics from the GLM output and significantly activated voxel counts for all 15 subjects. T-statistics: using the dHCP pipeline, all grey matter ROIs had an increase in mean t-statistic. The maximum t-statistic (in parentheses) increased in all regions using the dHCP pipeline, except the PoCG. # active voxels: the dHCP pipeline also resulted in an increase in the number of significantly active voxels using all three thresholding approaches. Voxel is FDR corrected; cluster and TFCE are FWER corrected. ACC = anterior cingulate cortex; PoCG = postcentral gyrus; TFCE = threshold free cluster enhancement.
