Just a simple Fourier Transform?
Hi,
I just want to make a simple fourier transform, yet I m not able to make one :-( The data set is multidimensional - but I tried with a simple
x y
x1 sin(x1)
x2 sin(x2)
...
set, load the set and try the fourier operator, but I get the error:
best regards,
Stever

G Jan 24, 2010 5:54:55 PM: [Fatal] ArrayIndexOutOfBoundsException occured in 1st application of FourierTransform (FourierTransform)I really don't see where the problem is here, because there are no options for me than just reading data and as a second operator the fourier module which has no settings at all :-(
G Jan 24, 2010 5:54:55 PM: [Fatal] Process failed: operator cannot be executed (16). Check the log messages...
best regards,

could you please send me your example process with the sinus generator?
I guess, there's something broken during the migration on RapidMiner 5.

I just used openoffice to create a file to test the routine. Its only a few periods, but I can attach it anyway.
At the moment I use rm 4.5 with linux.
When I insert a breakpoint after the data source and plot it, everything looks okay.
could you please post your process here, so that I can start without having to guess what you have done?

it seems to work with a generated example set. Please try to reproduce the error on a generated example set and post this process again. I cannot start your process without the data.
