Hi Annick,
This is covered in the FSL course practical here:
http://fsl.fmrib.ox.ac.uk/fslcourse/lectures/practicals/feat3/index.html#motion
For the outliers, you need one EV (column) for each outlier timepoint,
with a 1 for that time point, and 0s everywhere else. Then an extra 6
evs for the motion parameter estimates. Column names and order do not
matter, although it is useful for yourself and your colleagues to use
sensible ordering/naming conventions.
Cheers,
Paul
