Dear Bas,
yes, you will have to set SPM.xBF to some arbitrary values. Given there
is no substantial flaw in my understanding of SPM, user specified
regressors are not affected by SPM.xBF, as they will not be convolved
with any basis function. Hence, construction and estimation of your
design should be independent of the values assigned to SPM.xBF.
Best,
Thomas
