Hi,
I have performed a registration between a fa image and an anatomy image,
which works nicely. The transformation is saved in "mytrans.mat" as a 4x4
matrix T.
Now, I want to transform another object (some dti tracks) into the anatomy
domain using the SAME transformation. I carry this out in Matlab, by
multiplying T with the coordinates c = [x y z 1]' of my tracks
c(anatomy) = T*c(dti)
However, the tracks are slightly translated in one of the main
directions(x,y or z). Have I missed something about the transformation and
how it works? What can the problem be?
Best regards
Erlend Hodneland
