I looked at some structures and the absolute differences range from 8-35 mm^3. They are quite small but I was surprised to see any difference since they are the same scan.

Thanks, Tamara

Hi Tamara

can you let us know how big the differences are?

I don't understand what the problem is. Can you elaborate?

I have attached the files (Via Google Drive since they are large). They are from the same participant.

Thank you again, Tamara
