Hi FreeSurfer,
We have extracted the surface area using aparcstats2table.
1. The ROIs extracted are by default the White Surface Area, correct?
2. Why does the WhiteSurfArea (default average) have decimals but not the surface area of the different ROIs? When taking the SUM of all the ROIs, it does not equal the WhiteSurfArea and I am thinking this must be due to the decimals?
Best Regards Kasper

Correct.

No real reason. Whoever wrote the program that printed them out deliberately set it to have no decimal places. It is not clear why
