Hi Doug,
If you use flirt to apply a transformation and the reference is a
smaller
size (in voxels but not in mm) then it will do this downsampling for
you -
including appropriate pre-blurring before resampling.
You can also do it with the gui ApplyXFM which allows you to type
in the number and size of the output voxels rather than make an image.
All the best,
Mark
