Your input view needs to have at least 2 time steps, which will be
interpreted by the plugin as the real and imaginary parts of a complex
field.

 From the documentation:

"Plugin(HarmonicToTime) takes the values in the time steps `realPart'
and `imaginaryPart' of the view `iView', and creates a new view
containing (`iView'[`realPart'] * cos(p) - `iView'[`imaginaryPart'] *
sin(p)), with p = 2*Pi*k/`nSteps', k = 0, ..., `nSteps'-1. If `iView' <
0, the plugin is run on the current view."

You can try it out on "tutorial/view1.pos" for example.
