Hello,
I have caculated Reho of seven participants who took twice scan a week apart, and then i want to caculate the test-retest reliablity with Dpabi using ANOVA model. In the GUI frame, I put seven data, smREHO, which were taken in the first time, into Rate-1 Images, and the other data into the Rate-2 Images, and then clicked Compute button. But, when the icc was all zero. You can see how I put the data in the following pictures.
Is there anyone can tell me why and what should i to caculate the right result?
Thank you very much!

Hi Jason,
Hi Jason,
You can perform a paired t-test to see if there is any systematic differences.
