Usage #1: 3dTwotoComplex [options] dataset Usage #2: 3dTwotoComplex [options] dataset1 dataset2

Converts 2 sub-bricks of input to a complex-valued dataset. * If you have 1 input dataset, then sub-bricks [0..1] are

used to form the 2 components of the output.
  • If you have 2 input datasets, then the [0] sub-brick of

    each is used to form the components.

  • Complex datasets have two 32-bit float components per voxel.

Options:

-prefix ppp = Write output into dataset with prefix ‘ppp’.
[default=’cmplx’]
-RI = The 2 inputs are real and imaginary parts.
[this is the default]
-MP = The 2 inputs are magnitude and phase.
[phase is in radians, please!]
-mask mset = Only output nonzero values where the mask
dataset ‘mset’ is nonzero.

Notes: * Input datasets must be byte-, short-, or float-valued. * You might calculate the component datasets using 3dcalc. * At present, there is limited support for complex datasets.

About the only thing you can do is display them in 2D slice windows in AFNI.
