"Data to Series - Error: No value series in input example set"
I have an Example Set with about 100 examples and 25 regular attributes.
I would like to convert every attribute data into a series, and to obtain de Fourier Transform of every series.
I have used the "Data to Series" Operator, but it says "Process failed. No value series in input example set"
What should I do?
Thank you very much!!
Best regards, Rosana
