Hi proxquad,
Such data organization (stored in a worksheet) is called a "virtual matrix" in Origin.
You can convert it to a regular matrix by selecting "Worksheet> Convert to Matrix>
Direct" menu, and set the options like:
- Data Format = X (or Y) Across Columns
- X (or Y) Values in = First Data Row (or Column Label)
- Y Values in First Column = YES
Once your data is converted to a matrix, you can run the 2D FFT by choosing:
"Analysis> Signal Processing> FFT> 2D FFT" menu (in OriginPro).
I hope this helps.
