Hi I have been using FLIRT to register my T1 and DTI images to each other but keep running into
problems. The registered images produced are always very close to what they should be when I
overlay them onto the T1 image. The problem I have is the matrixes don't always reflect the
registration image. I create a CC ROI mask on the T1 image/registered image and use the matrix I
produced to convert it back into difusion space. Now when I do this with some subjects the ROI will
be spot on the CC and for others it will be off somewhere in the cortex or even just into the black
void. I can't seem to find any rhyme or reason for this and the variation of how off the matrix is does
not seem to be consistent, any help figuring this out would be appreciated. Thanks.
