Hi,
I guess it will depend on what you wanna do with the data.
It won't be easy to combine the two runs - because of voxel intensity AND
diffusion gradient issues. So I would probably analyze the two runs separately
and combine them (e.g. by using the FA image or whatever) later on. Having said
this, you may wanna try the CATNAP toolbox from the BIRN (which uses flirt, of
course;).
Cheers-
Andreas
Hello,
I have DTI data collected with 68 ( 8 no
diffusion scans) different directions, with two consecutive scans, that
are interleaved to cover the whole brain. In some of them the subject
moved from one scan to the other so that when I reconstruct the image there is
an obvious shifts between the 2. How can I correct for that. Can I
use Flirt with 6 DOF only to register one to the other and then scramble
them into one image? Is this transformation going to change the
voxel values due to interpolation?
thanks for the
help
Paul
