SPM can't find xKXs. This is the filtered and whitened design matrix.
Perhaps something has gone wrong with the whitening or filtering process.
You could, perhaps, turn off the AR estimation stage (ie. the whitening)
if you're doing first level fMRI or turn-off non-sphericity options if you're
doing PET/2nd level fMRI.
But really, I;m not sure what's going on !
Best,
Will.
