Hi Maria, can you elaborate on exactly what you have done? Is the data
the same and you are only changing the version of QDEC? What is the
nature of the difference? Can you send pics or stats?

Hi,
I'm learning how to use QDEC and was comparing results that it produces under
FresSurfer 5.0 vs 5.3. I know the 5.0 has an option for either DODS or DOSS
method of producing a design matrix, while the 5.3 only has DODS. This
suggests that results should be identical (or at least similar) across
versions if I select DODS. However, I'm getting very different results based
on the version I select: complete lack of differences across groups in 5.3
and a predicted pattern of differences in 5.0 using DODS. I'd like to
understand where the differences are stemming from -- any ideas?
Thanks in advance!
Maria
