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.

version: 1.1.0

Inputs:

    [Mandatory]

    [Optional]
    args: (a unicode string)
            Additional parameters to the command
            flag: %s
    environ: (a dictionary with keys which are a newbytes or None or a
             newstr or None and with values which are a newbytes or None or a
             newstr or None, 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: (u'stream' or u'allatonce' or u'file' or u'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
