Dear All,
I have some basic questions about groups analysis for cortical thickness, and I looked over the list and tutorial, but still have questions. I have two groups, experimental and control, and both were tested before and after training... I plan to use qdec to run the group analysis, and I finished the recon-all, and -qcache processing for each subject. My question is that:
1.Is it necessary to select a ROI prior to my cortical thickness analysis?
no
2.For the .dat text file, which stats (for cortical thickness) output should I use for the continuous factors such as left hemi thickness, right hemi thickness?
If you want to use the thickness as an dependent variable (sounds like you do), then do not put thickness in the .dat file. doug
Thanks, Catherine
