I am wondering if there a way to account for repeated measures when running a QDEC analysis. I have 60 scans taken from 39 subjects (ranging between 1 scan per subject to 5 scans per subject).

Over all I am trying to corrlelate freesurfer measures of thickness and volume with scores from a language test. I am also corrected for age and gender.

Is there anyway you can think of to correct for the extra scans?

Thanks,

Matt
