Would there be a way to extract ROI difference values for a single subject (i.e., somehow use the Analyze ROIs) function with a single subject difference image)? I know statistical analyses would be fruitless, but it could be helpful to obtain thickness change values within the various ROI atlases in CAT12.
Thanks,
Jeff

I would like to get statistics of the thickness loss/gain overtime. I've created and estimated the design, but viewing the results is where there's an issue. Below is the error message I receive:
