Hi,
I am trying to register the resting state scan of multiple subjects to MNI space. After motion correction and high-pass/low-pass filtering, I have tried to input subjects resting scans into the FLIRT linear registration tool. Using the FLIRT GUI creates the following command:
flirt -in filtered.nii -ref MNI152_T1_2mm_brain -out filtered_reg.nii.gz -omat filtered_reg2.mat -bins 256 -cost corratio -searchrx -90 90 -searchry -90 90 -searchrz -90 90 -dof 12 -interp trilinear
This works well but registers only one volume of the functional data. When I use the ‘-applyxfm’ option, FLIRT registers all of the volumes, but the brain becomes off center and cut off. Am I using this command correctly for a 4D image?
Would it be possible to use FEAT somehow for registration? I was under the impression that the filtered_func_data.nii.gz from a lower level FEAT is not registered to MNI space.
Thanks,
Lars
