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
