Hi Ilana

have you visually inspected the asegs? I would make sure that there are no systematic and/or biased segmentation results in which the putamen/insula are misassigned so that one is "stealing" from the other.

Hi there, I have two behavioural variables that are inversely related to each other. One was correlated with thinning of the posterior insula (using glm_mri), while the other is positively correlated with the putamen volume (extracting aseg tables and running in SPSS). The region of the insula is basically adjacent to the putamen. So i'm wondering whether these findings are related, and how would i go about teasing this apart.
