That's right - it's the timeseries of the raw data fed into the higher level analysis, which is the
lower-level cope values.

Yes. An easy way to do this is to take the co-ordinate/mask of the voxel (in standard space) and
use that to feed into a Featquery analysis of each of the first-level FEAT runs. You can setup all of
these with a single setup of the GUI.
