tensor2metric [ options ] tensor

Generate maps of tensor-derived parameters.
tensor: the input tensor image.
可用options

• -adc image compute the mean apparent diffusion coefficient (ADC) of the diffusion tensor. (sometimes also referred to as the mean diffusivity (MD))
• -fa image compute the fractional anisotropy (FA) of the diffusion tensor.
• -ad image compute the axial diffusivity (AD) of the diffusion tensor. (equivalent to the principal eigenvalue)
• -rd image compute the radial diffusivity (RD) of the diffusion tensor. (equivalent to the mean of the two non-principal eigenvalues)
  等。

dwi2tensor [ options ] dwi dt

Diffusion (kurtosis) tensor estimation.
推荐使用options

• -mask image only perform computation within the specified binary brain mask image.
  mrconvert [ options ] input output
  Perform conversion between different file types and optionally extract a subset of the input image.
  推荐使用options
• -fslgrad bvecs bvals Provide the diffusion-weighted gradient scheme used in the acquisition in FSL bvecs/bvals format files. If a diffusion gradient scheme is present in the input image header, the data provided with this option will be instead used.

dwi2mask [ options ] input output

Generates a whole brain mask from a DWI image.
