Hi all,
I have been trying to reduce the spm affine registration procedures
for a 2D application and
I have the following doubt: If Mg and Mf are the matrices defining the
geometry of the reference (g)
and floating (f) image, and if M is the matrix obtained by the registration
procedure, what matrix combination
should I provide to the reslice routine to transform f in the space of g
with M: would it be inv(Mg) * M * Mf ?
Also, if the dimensions of the image are in microns (and mm, as they are in
neuroimaging) should I be creating
Mg and Mf in any special way?
Thanks a lot,
Sid.
