Before starting this tutorialΒΆ
Make sure that you have the following files in your working directory:
T2 and T2* files (used in the initial registration to template for T2* data)
single_subject/data/t2/warp_anat2template.nii.gz
: The 4D warping field that defines the transform from a T2 anatomical image to the template image.single_subject/data/t2/warp_template2anat.nii.gz
: The 4D warping field that defines the inverse transform from the template image to a T2 anatomical image.single_subject/data/t2s/t2s.nii.gz
: A T2* anatomical image of the spinal region.single_subject/data/t2s/t2s_wmseg.nii.gz
: A binary mask for the white matter segmentation of the spinal cord.
MT files (used when improving MT registration with T2* warping fields)
single_subject/data/mt/mt1.nii.gz
: A magnetization transfer image with the off-resonance RF pulse applied.single_subject/data/mt/mt1_seg.nii.gz
: 3D segmentation of the spinal cord, corresponding to the MT1 image.single_subject/data/mt/mask_mt1.nii.gz
: 3D binary mask surrounding the segmented spinal cord, corresponding to the MT1 image.
You can get these files by downloading data_improving-registration-with-gm-seg.zip.
Open a terminal and navigate to the
single_subject/data/t2s/
directory:
cd {PATH_TO_DOWNLOADED_DATA}/single_subject/data/t2s/
