This tool registers multiple moving images to a single target image using the Greedy Registration technique [1]. This tool is also available from the web on the CBICA Image Processing Portal. Please see the experiment on the portal for details. REQUIREMENTS:
- A Target image.
- Up to 5 moving images
USAGE:
- Launch the "Registration" dialog from the "Preprocessing" menu.
- Customize the parameters (Metrics, Radius and Iterations) as needed; for details regarding the parameters and their usage, please refer to the Greedy manual [2].
- Specify the moving images (up to 5) and their respective output images.
- Click on 'Register'.
- The output image is saved in the specified locations.
- This can also be used from the command line:
${CaPTk_InstallDir}/bin/Preprocessing.exe -i moving.nii.gz -rFI fixed.nii.gz -o output.nii.gz -reg Affine -rME NCC-2x2x2 -rIS 1 -rNI 100,50,5
More usage options are available via the greedy
command-line executable (see documentation for it here), which is present in ${CaPTk_InstallDir}/bin/
.
