[Camino-users] FA and MD alignment, registration of Freesurfer labels

[Oren Geri]

Hi,
I
have a few questions about creating connectivity matrix with Camino and Freesurfer
labels.
 
First,
I followed the tutorial instructions to create fa.nii and md.nii files.
I
checked these files using SPM8 display command. The images didn't seem to be
aligned, also I got different "Origin" and "Dir Cos" values
for the images and a warning : "shears involved" message (This
problem doesn’t occur using the tutorial data).
 
Second,
I used Freesurfer for labeling different volumes and SPM to register the labels
file "aprac+aseg.nii" using "orig.nii" (the structural
file) as source and the B0 data as reference.
I
viewed some of the streamlines created by Camino (following the tutorial using dtfit) and volumes
from the registered image of labels with Paraview. It seems that there is a registration problem
since the streamlines appear shifted from the place they should be. 
Thanks
a lot,
 Oren
