I coregistered manually a aparc+aseq.nii file to my DWI-space with tkregister2. I saved the .dat file and applied it later to the T1 image in order to apply the same spatial coregistration as to the aparc+aseg. For woth the aparc+aseg and the T1 I used the command mri_vol2vol --mov was the b0image --targ was the aparc+aseg and T1 respectively --o was the output (a .nii in both cases) --reg was the .dat file and at the and --inv.
While the aparc+aseg registration to the b0 worked, the T1-registration gave a false result (altough it had the same dimensions and was in the same space with the aparc+aseg).
What am I doing wrong? Is the mri_vol2vol command the wrong one? I want to apply the same changes as to the aparc+aseg, as they are saved in the .dat file.
Thanks a lot, Constantin
