Hi folks - trying to do Cross-Correlation on 2 large files, must convert from I16's in the 2 files, scale all by a range value, divide by a full-scale single float, perform the cross-correlation, and display the result.For 2 files, each with 8M 2-byte I16's, I get a -20001 error from the cross-correltation function, "not enough memory".My machine has 2GB of RAM in it, but just before the function barfed, Windows Task Manager told me the LabVIEW memory allocated was 682MB.My 3 questions are1) Why is the function barfing when I still have almost another free gig of memory?2) Why is LabVIEW sucking up so much memory?3) Am I doing anything silly to create more copies than I need to do the job?any insight would be appreciated, thanks, paul

LabVIEW gobbling my memory??

You're right - 16M works if I cast the FFT output as scalar SGL or DBL, but barfs if I make it complex.

Looks like the Power Spectrum, Inverse FFT, and Cross Spectrum functions have an 8M sequence limit.
