I thought it was disabled in 5.3, thanks for the heads up.

Hi Doug,
I'm using version 5.3. I had read about the bug but the release notes for
5.3 didn't mention not using DOSS in Qdec, so I thought the issue must have
been resolved. If not, I'll let my colleagues know as I believe some of
them are still using DOSS in Qdec.
Cheers,
Cassie

Hi Cassie, DOSS has a bug in QDEC so please do not use it. I thought we
disabled it. What version are you using? If you want to compare DODS vs
DOSS, then you'll have to use the command-line stream (mris_preproc,
mri_surf2surf to smooth, mri_glmfit, and mri_glmfit-sim)

Hi Doug,
I am carrying out some correlations between cortical thickness and
cognitive ability, and had a question about the use of DODS vs DOSS for my
analysis with Qdec. From reading some of the forums, it seems as though
DOSS should be used when there are no interactions present. I am including
DODS: Different offset, different slope; This models (potentially)
differing slopes against the covar and allows you to check for a group-
by-covar interaction
DOSS: Different offset, same slope; This assumes that both groups have
the exact same slope against the covar (but differing intercepts).
Hello all,
I'm attempting to run a cortical thickness group differences test in qdec with
a covariate, and have been told that in order for it to match up with similar
anlyses in SPSS, amongst other things, I'll have to ensure that I match on
"DODS" vs. "DOSS." What are these two options, and
