Create DISCO deformation field from subjectA to subjectB

This tool creates an deformation field mapping data from subjectA space into subjectB space, considering DISCO deformations.

Description

1. Choose the type of the study (Native or AfterDISCO).
2. Select the study directory of the experiment
3. Choose the nobias of subjectA.
4. Choose the nobias of subjectB.

If the subjectA (subjectB) to be considered has been pre-processed before the Morphologist processing (add border to initial data), it is possible to estimate the global deformation field using the Other mode of the choice_native_image_A (choice_native_image_B) parameter. In this case, add the initial data (in native_image_A (native_image_B)) and the transformation representing the added border (border_nobias_A (border_nobias_B)).

• Choose Morphologist nobias if you want the deformation field to have the geometry of the data that was used as an input to DISCO (i.e. the image processed through Morphologist).
• Choose Other for using a different geometry (e.g. an image with a different field of view, such as a cropped image).
