Hi All,
Referred to Karl's email on 17 Mar 05, it suggested that it may be possible to
use PET model to analyze a long TR fMRI data set. As pointed out by Karl in
that email, however, one should include the low frequency confounds in the
design matrix. I would like to ask how can I put the low frequency confounds
(i.e. drift terms) in the PET design matrix? Do anyone have any idea how to do
that in SPM2?
many thanks,
savio
