Extract part fails for single point (ValueError)

Created by: Famlam

1. Have an arrayed spectrum (for example a spectrum where the CP contact time is varied), i.e. a semi-2D. In my case, the number of FID's was 3 (so a 3x2200 dataset)
2. Want to extract only the second FID for further processing, so:
3. Switch to the 'indirect dimension'
4. Matrix -> Extract part
5. Fill in Start index = 1, End index = 1, Step size = 1 (note: index = 1 refers tot the second spectrum) (Alternatively, use the mouse to click left and right of the second data point; you'll also get 1 in every input box)
6. Get the error below
