Hi all,
I have a problem with my design matrix (see attached jpeg for
reference)... As an example of the problem: the first regressor there are
supposed to be 16 events spread out across the whole session. However,
only 6 onsets are shown here. This is the case for all of my regressors as
far as I can see. I checked over the design spec (.mat and .m files: I can
email these to anyone who needs to look at them but they are too large to
email here) and all seem to be specified correctly. Next I used 'review'
and found that the explore option shows that for the first regressor 6
onsets were extracted (see attached jpeg). I am completely baffled by this
and don't know what to do next. I even uninstalled spm, reinstalled and
re-ran the spec with no improvement.
Can anyone help?
Cheers,
Lorelei
