RE: Test if BOLD signal in a specific ROI is correlated with my PET signal of a certain ROI
Dear June,
Selecting 'AllSubjects' and your 'PETvalues' covariate in the subject-effects list, and entering a [0 1] between-subjects contrast, will evaluate the correlation across subjects between the PET values and functional connectivity
Hope this helps

Dear all,
I would like to investigate if my resting state BOLD signal in a certain ROI is correlated with the PET signal in a certain ROI.
For this analysis, I have resting state fMRI data of 20 subjects.
I can add for each ROI the ROI PET values as a second level covariate, but how do I test if these values are correlated with my resting state signal?
Thank you for your help!
