Hi, there,

I have a question about FS longitudinal stream,

Suppose I have two volumes A and B, B is the copy of A, but has been scaled (say, 1%) at each direction.
Both of them have been cross-sectionally processed. If we send them to the FS longitudinal stream, what will happen?
For example, if we look at the hippocampal volume of A and B (longitudinal result),
Should their percentage difference be around 0% or 3%?

Thanks!
Guang
