This may be helpful to bring the images into a standard orientation at start.

Initial rearrangement of the REF images by mirroring and rotations.

Initial reslicing of the INP images with arbitrary translations and rotations in the reslicing panel. This functionality is used for manual matching.

Initial reslicing of the REF images by arbitrary translations and rotations with the reslicing panel. For instance, tilted reference images should usually be straightened before matching.

Open the IMAGE ALGEBRA sub-page.

Open the VOIS sub-page.

Start the 2D scatter plot tool.

Start the 3D scatter plot tool.

Hide the control area for more image space. Activate a second time to show controls again.

Context-sensitive help, pointing to the html documentation.
