you can try dividing it. Run this on subjects for whom you do have area and see how well it does

Dear Douglas,

Thank you for your quick answer!

The thing is, we don't have access to the original surface area files which were created by FreeSurfer anymore. Thus, we were wondering if we can calculate a region's surface area if we have its volume & cortical thickness values. Is that possible?

Thank you very much!

We output surface area separately both as a map and as statistics
