Dear FreeSurfer experts,

I was running group interaction (for diagnosis and birthplace) in QDEC with gyrification as a dependent variable and age, gender as nuisance factors. 

In diagnosis, we have 2 groups: i) schizophrenic patients ii) healthy volunteers.

Similarly, birthplace has 2 groups: i) urban ii) rural birth

For the above-said design, I got reddish yellow color results in the display tab of Qdec.

So, my query is that do results indicate that patients who were born in urban have a higher gyrification index than healthy volunteers who born in urban or something else? Do I sound correct in decoding the interaction results? If not please let me know the exact meaning of the results.

Looking forward to hearing from you.

Thanks,

Vittal
