HOutliers are data values that are very different from other
values in the same time series
åto3d reports sub-bricks (time points)
that have a lot of outliers
åYou
should use AFNI to look at these time points to see if there are major problems (e.g., head motion, scanner artifacts)
åto3d -skip_outliers option lets you
skip the outlier detection step
åUtility
program 3dToutcount can also
report outliers and can even make a dataset with the Ôoutlier-nessÕ of each voxel value
