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
