You can register the brain.mgz (and so all conformed volumes) to MNI152 with the mni152reg script. This will create $SUBJECTS_DIR/$subject/mri/transforms/reg.mni152.2mm.dat. If you have a registration for the CT to freesurfer space, then you can combine them like: Rfinal = inv(Rct)*R152 with mri_matrix_multiply -iim Rct -im reg.mni152.2mm.dat -om Rfinal.dat Make sure to check with tkregister2 --mov ct.nii --reg Rfinal.dat --targ $FSLDIR/current/data/standard/MNI152_T1_2mm.nii.gz You can then used mri_vol2vol to put the CT directly into the 152 space.
