Hi David,

Demeaning motion parameters should actually make no difference
in the results, except for affecting the constant baseline terms
(maybe you care about them). To take it further, detrending each
run of the motion parameters should have no effect, up to the
polynomial degree applied as baseline in the regression.

It should not affect the other beta weights or statistics at all
if the regressors are linearly independent.
