Yes, this is probably because the ReML is failing to find a good match
to your covariance structure, therefore generating a rank deficient
estimate of the covariance, and this ends up generating - er - the
error you see. Try switching your covariance estimate from ReML to
the fmristat method - see:
http://marsbar.sourceforge.net/faq.html#fmristat
Let me know if that doesn't work...
Best,
Matthew
