Hello,
I went on the FS course in Amsterdam recently. I have run a QDEC analysis to see whether cortical thickness differs between my two groups. I have two questions:
1. I put in the lh_bankssts_thickness as my continuous variable. The display outputs results for whether average thickness differs between my groups. The significant clusters appear in areas which are far away from the lh_bankssts. Is this correct? Does the design somehow look at overall cortical thickness in the lh even though I have only specified the lh_bankssts?
2. I can't see the button for controlling for multiple comparisons. From the wiki I believe this is supposed to appear under a scalar heading, but I can't see it. Do I need to add something in order to do this?
Thank you very much.
Best wishes, Clare
