Is the error message not clear what the problem is?

Hello,
I have 2 groups (group 1 = 3 members, group 2 = 12 members) and I did
like to regress out the effects of groups + other variables by using
doss. However, whenever I specify doss with the mri_glmfit command, it
gives me an error message (see below). I saw that others have
experienced similar issues without any solutions. How can we solve
this? Any insight is appreciated.
Best,
Paul
