Dear Ekkehard,
we have tried to write fnirt to be completely independent of scale/
size of the brains. However I have personally never tested that
properly (by running it e.g. on rats) so I think the "safest" way
would be for you to simply scale all voxel-sizes by 10.
There has been some questions about rat/mouse fnirting in the past so
if you seek the archives you might find these postings and also mail
addresses for people using it on rats/mice who you can ask for advice
and their experiences.
Good luck Jesper
