Thanks Doug.

I guess this is a common situation where two or more parameters only
apply to one group (in this case patients) and are zero or constant in
the other.

Dear Doug,
Thanks for the answer. I deliberately chose not to demean.
With demeaning I get the same error (see below). Any suggestions?

Design matrix --

1.000 0.000 -0.800 0.000 11.962 0.000;
1.000 0.000
It looks like the 4th column is always -0.9 and the 6th col is always
-9.138 which makes them redundant with column 2 and causes the error.

Try demeaning your covariates. By demeaning, I mean to compute the mean
across all subjects, then subtract the mean from all values (for each
covariate).
