Hello-
I would like to align FA volumes from patients as accurately as possible.
One approach would to be determine a study-specific target - the subject in
the group which is the "most typical". I have found the registration tools
as part of the TBSS stream, but would really like to stay with a linear
transformation.
Is there a way to calculate the overall transformation done between 2
volumes during a linear transformation (6 dof)? I found the rmsdiff function
but that doesn't seem to be doing quite the right thing, as I want to be
able to put in one transformation matrix and find out how large of a
transformation was necessary.
Or, do you have other suggestions for linear alignment of FA images?
Thanks,
Katherine
