title: MaxCurvature-Hessian (DTIProcess)

category: Diffusion

description: This program computes the Hessian of the FA image (–image). We use this scalar image as a registration input when doing DTI atlas building. For most adult FA we use a sigma of 2 whereas for neonate or primate images and sigma of 1 or 1.5 is more appropriate. For really noisy images, 2.5 - 4 can be considered. The final image (–output) shows the main feature of the input image.

Optional Inputs:

  • args (a string) – Additional parameters to the command. Maps to a command-line argument: %s.

  • environ (a dictionary with keys which are a bytes or None or a value of class ‘str’ and with values which are a bytes or None or a value of class ‘str’) – Environment variables. (Nipype default value: {})

  • image (a pathlike object or string representing an existing file) – FA Image. Maps to a command-line argument: --image %s.

  • output (a boolean or a pathlike object or string representing a file) – Output File. Maps to a command-line argument: --output %s.

  • sigma (a float) – Scale of Gradients. Maps to a command-line argument: --sigma %f.

  • verbose (a boolean) – Produce verbose output. Maps to a command-line argument: --verbose.

Outputs:

output (a pathlike object or string representing an existing file) – Output File.
