AutoCorrelation input sequence limit of 5 million points ?

[Steve Parus]

The AutoCorrelation vi gives error -20010 MaxXformSizeErr "The maximum
allowable transform size has been exceeded." if its input sequence
array size exceed about 5 million points. Is this an inherent
limitation ? If so, why ?

This may have been a memory error on your machine. I'm running 6.1 on XP and have about 228MB of RAM. I ran this VI and input an array of 10,000,000 points and it ran correctly. You may want to try this on another machine. Also, make sure that you have Virutal Memory enabled so that you will not run out of memory as easily.
