Hi Mike,
> I am trying to open (put in memory) only part of a large image. The image I'm trying to use is a 2D image approximately 30Gb and is composed of many tiles. I do not have access to the individual tiles, I only have access to the finally stitched image. I need to do some automated cropping on this image but I first need to be able to work with this size of image.

Yes, this can be done if you are using the Bio-Formats importer plugin
(
http://loci.wisc.edu/software/bio-formats) to open the file.
Just select the "Crop on import" option in the "Bio-Formats Import Options"
window, then enter the XY coordinate of the upper-left corner along with the
width and height of the part of the image that you want to view.
Regards,
