Great thanks for all the replies,
I have a more than 50 subjects, and before trying to use any other tool than SPM, is there any SPM function, or can we write one, that takes the motion parameters file(s) (i.e. realignment-parameters), and give a statistical estimate showing how good or how bad our MRI volumes are?
Cheers,
-Rawi

That much motion will not just affect your data, it will have a potentially dramatic affect on your data.
