[Mristudio-users] loading AIR files

[XIN LI]

Sarah,

The "AIR" file is not an image file. It has the transformation information and its format is special. You cannot open it using Landmarker but you can apply this AIR file to the loaded subject images and get updated images by clicking the button "load transformation matrix".

The images that named "updated_filename" are the registerd images. The original image is still in the subject window. There is a image list in the right pannel. You can select the image that you want to display in the views.


Hope this will give you some help.


Xin
