Hi AFNI experts, I have tried to look for information on how to do my analysis but can't find anything specific, so I here is my question:

I have PET data collected for 14 participants at rest. I also have measurements of behavior for each participant (impulsivity scores for example). What kind of analysis can I do to examine the relationship between PET signal and clinical scores? Looking through the message board, I saw that most of the time analysis involves "regressing out" the covariate, but in this case, I would like to know the relationship of that covariate with PET signal.

Can somebody point me in the right direction for this analysis? Thanks! Jazmin.
