Dear FSLers:
I have a general question about VSCALING computed during SIENAX. I
appreciate if someone can help me with this.
From what I understand, a skull and a brain are registered with the
standard skull and brain by using affine transformation in FLIRT.
Is VSCALING determined by the determinant of the affine transformation?
Also, is it safe to say if a subject consists of skull that is twice the
size of standard skull, then his/her normalized GM volume would be twice
as much relative to the GM volume in normalized brain.
Thanks,
Hedok
