Wraps command ** maxcurvature **

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.

Inputs:

[Mandatory]

[Optional]
args: (a string)
        Additional parameters to the command
        flag: %s
environ: (a dictionary with keys which are a value of type 'str' and
         with values which are a value of type 'str', nipype default value:
         {})
        Environment variables
ignore_exception: (a boolean, nipype default value: False)
        Print an error message instead of throwing an exception in case the
        interface fails to run
image: (an existing file name)
        FA Image
        flag: --image %s
output: (a boolean or a file name)
        Output File
        flag: --output %s
sigma: (a float)
        Scale of Gradients
        flag: --sigma %f
terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
        Control terminal output: `stream` - displays to terminal immediately
        (default), `allatonce` - waits till command is finished to display
        output, `file` - writes output to file, `none` - output is ignored
verbose: (a boolean)
        produce verbose output
        flag: --verbose

Outputs:

output: (an existing file name)
        Output File
