Re: Limit in waveform data size?
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) Eric
Re: Limit in waveform data size?
Question: - Is there a limit in the amount of data that can be but into wavevorm data type instance - Is there a limit in the append function - Am i getting stuck on limitations on memory in Labview or windows You probably want to use the task manager or other Windows tools to see just how much memory is being used. My guess is that you get the message when the process hits 2G of virtual memory, and that is the limit imposed by the OS. Keep in mind that when you are manipulating large arrays that copies can be made, and to display them copies must be made. These can be minimized to a point, but at some point the convenience of dealing with a simple arrays takes too much memory and you need to operate in blocks or on decimated data. There are some pretty good articles on dealing with large arrays on the NI web site. Greg McKaskle
