Hi Dong,
What is the age range that you are working with?

No, not that I know of.
Also I expect that it also depends on other factors (like image resolution, quality, subject anatomy etc) .

Hi Martin Thanks a lot for your reply! Is there any reference that the longitudinal processing would fail if the difference in head size exceeded any certain value?

it can work, if time points are close to each other (so not much head growth). Feel free to try, but make sure you are carefully looking at the surfaces, that no gray matter is clipped in later time points.
The alternative is to only do cross sectional processing.

As it is mentioned in the documentation that ‘pediatric data violates the fixed head size assumption’ for the current longitudinal stream. Is there any solution for the issue now?
Thanks
