Hello,
As a PhD student, I send you this mail because i am meeting a misunderstanding with QDEC. In a few words :
I made an analysis thanks to the QDEC tool :
* I tested a correlation between an inhibition score and cortical thickness, corrected for age
(continuous = inhibition score ; nuisance = age ; smoothing = 25 and FDR corrected)
*** ***** ** *********** * *********** ******* *** ********** ***** *** ******** ********* ** ***** ****** ************** *****
* then, I realised a ROI analysis. I extracted different statistic values from this orbito-frontal region following your wiki (aparcstat2table).
Thus, I obtained for each participant, the average value of medial orbitofrontal cortical thickness.
Finally, I made a multiple linear regression analysis on R software which is a statistical software. Surprisingly, « R », indicated that it doesn't exist any correlation between the right medialorbito frontal thickness values and the inhibition scores. I don't understand why.
Can you help shed some light on this issue ?
Yours sincerely
Marine Moyon
