Dear Carnivorus: I would venture to say that perhaps there is not enough memory to complete the operation! :) All snide aside, working with large arrays takes some serious number crunching. You might try twiddling your swap file size (on the Advanced properties tab of My Computer in win2K and later). However, you're probably bumping up against the absolute limit of the OS. If there is ANY way of dividing and conquering your data so as to not have to deal with such a large array, I think you should invistigate it. YOu may find you don't need anywhere near the samples you think you do. (voice of experience,here!) Or perhaps you don't need the dynamic range. (On most DAQ cards, you can't change the number of bits, but you might be able to use a card with fewer than you're currently using)
