Hi,

We are concerned about differences of cortical thickness when we process the same scans in freesurfer 4.5 and 3.02. We have attached an excel spreadsheet of the differences in thickness between 4.5 and 3.02 using the mean thickness of parcellations of both versions in both hemispheres. The difference in the paracellations vary from 3-11% between the versions.

Are these findings reliable and explainable in choosing freesurfer 4.5 as our final version.  

Any comment are greatly appreciated,

Thanks!

Rune
