Dear Marco,

> By default fsl_motion_outliers outputs a "confound matrix" in which a new column is created for each volume identified as a motion outlier. Can anybody please explain to me why this would be preferable to collapsing all columns into one, containing multiple 1's, corresponding to each of the outliers? Wouldn't the latter approach have a lower impact on the degrees of freedom?
a single column would be equivalent to assuming that each “outlier movement” caused the exact same effect in the image. And that is clearly not the case.
