Hi,
I have the feeling that there is some misunderstanding of the previous
suggestions given earlier, but I may be wrong.
There is a plugin that is called "Virtual Stack Opener".
http://rsbweb.nih.gov/ij/plugins/virtual-opener.htmlwhich now is included in IJ in the File>Import>Image Sequence
(you check: Use Virtual Stack).
This loads one slice at a time from disk, so you would not need to load the
whole stack (and therefore would allow you to use stacks which are much
larger than your memory).
In a previous mail, you said that the virtual opener takes the same amount of
memory than loading whole the stack. Can you verify this? This should not be
the case because at any one time there is a single slice on memory.
But now you say that you are using a self-written plugin that loads the whole
stack, so this is not the virtual stack opener...
Here is all the information on how to increase the memory available for IJ:
