In some circumstances a set of images might have a mixture of left and right eyes and you may want to generate a montage for each without needing to separate the images into separate folders. In the following video, 15 images are loaded and the user does the following:
After loading the images, click on the "Select all " button at the bottom,
Confirm the software is configured for retinal images and montage output at the top right,
Select "Process" (wait several seconds up to fraction of minute)
Look at the montage image in the i2k Viewer application
Return to the dialog box in i2k Retina (about 68 seconds into the video) and click first on the list of "Aligned Images"
Click on the "Non-aligned Images" and look at the list of file names (notice they are all named with an "a")
Use a right-click over the "2a" image and select "Set as target" (1:21 in the video)
Select "Process" again. Notice it only takes 12 seconds to generate the second montage because the images have already been aligned to each other.
