After realignment, the regions that are masked (set to zero in all images in
the time series) are not included in the analysis. You can check what is
included just by displaying a realigned and resliced image.
More generally, you can check which voxels have been included in an analysis
by looking at the mask.img that is produced when the stats are run.
