The first step to use this module is to import the fixed image and the moving image (to be registered into fixed image geometry). To do so, click on ``open'' button on the very left of the toolbar. Please read carefully the welcoming page that explain how to proceed. The first image to import is the fixed image. It corresponds to the target image for the registration method. The second image to be opened is the moving image. It corresponds to the one that will be registered onto the fixed image geometry.
IMPORTANT : Please make sure that both the fixed and the moving image are in the same orientation before importing them.
The fixed image (target) is now shown on the right panel and the moving image is shown on the left one. Some flags remind you the name of the file on the top of each panel.
