In the previous examples, data came from one subject and one modality, so all images were in the same referential. With data from different subjects and modalities, it is more complicated, we have to take care about the different referentials. See Anatomist manual and a presentation about for details about referentials management.
Visualization of the anatomical MRI of 2 subjects in a common referential (Talairach AC/PC-Anatomist)

Fusion the 2 images. Notice that they are not well superimposed because they are not in the same referential.
Right-click on each image then Referential => Load => New.
Open the referentials window: Windows => Referential windows.
Draw a line with the mouse from the referential of subject01 to the red referential named Talairach AC/PC-Anatomist and choose the tranformation file:
data_for_anatomist/subject01/RawT1-subject01_default_acquisition_TO_Talairach-ACPC.trmDraw a line with the mouse from the referential of subject02 to the red referential named Talairach AC/PC-Anatomist and choose the tranformation file:
data_for_anatomist/subject02/RawT1-subject02_200810_TO_Talairach-ACPC.trmReturn to the window that displays the fusion and click on the menu Scene => Focus view on objects.
Now, the display of the 2 images must be consistent.
