Frida can transform the data in a variety of ways, ranging from simple operations on the axis to Fourier transformation.
The following page lists a description of the different commands available in the transformation menu t.

  • tu = conversion of units in x (and possibly in y)
  • tfc = Fourier cosine transform with Filon algorithm
  • tfs = Fourier sine transform with Filon algorithm
  • tff = Fast Fourier cosine transform
  • tfp = Fast Fourier complex transform
  • tfe = Fast Fourier transform of exponential
  • ts = (anti)symmetrize
  • tm = double by adding mirror image Y(-x)
  • tr = [not implemented] representation of complex numbers
  • td = [not implemented] deconvolution
  • tc = [not implemented] convolution
