Dear Experts.
I have a GLM which correlates a behavioural variable of interest with gray matter density across the whole brain. Using randomise, this produced a significant cluster.
How do I go about extracting values to make a scatter plot of the correlation between my behavioural variable and gray matter (for visualisation purposes)?
I know that I can extract the significant cluster from the corrp image, binarise it, then use that as a mask on the GM_mod_merg image, but as far as I know, I can only get the mean/SD gray matter value across this mask, per subject.
Could anyone advise please?
Thanks.
Sam
