DESCRIPTION

ComposeMultiTransform ImageDimension output_field [-R reference_image] {[deformation_field | [-i] affine_transform_txt ]}

Usage has the same form as WarpImageMultiTransform

For Example:

ComposeMultiTransform Dimension outwarp.nii -R template.nii ExistingWarp.nii ExistingAffine.nii

or for an inverse mapping :

ComposeMultiTransform Dimension outwarp.nii -R template.nii -i ExistingAffine.nii ExistingInverseWarp.nii

recalling that the -i option takes the inverse of the affine mapping

Or: to compose multiple affine text file into one: ComposeMultiTransform ImageDimension output_affine_txt [-R reference_affine_txt] {[-i] affine_transform_txt} This will be evoked if a text file is given as the second parameter. In this case reference_affine_txt is used to define the center of the output affine. The default reference is the first given affine text file. This ignores all non-txt files among the following parameters.
