Wraps command **AffineRegistration **

title: Affine Registration

category: Legacy.Registration

description: Registers two images together using an affine transform and mutual information. This module is often used to align images of different subjects or images of the same subject from different modalities.

This module can smooth images prior to registration to mitigate noise and improve convergence. Many of the registration parameters require a working knowledge of the algorithm although the default parameters are sufficient for many registration tasks.

                 {})
                Environment variables
        fixedsmoothingfactor: (an integer)
                Amount of smoothing applied to fixed image prior to registration.
                Default is 0 (none). Range is 0-5 (unitless). Consider smoothing the

        histogrambins: (an integer)
                Number of histogram bins to use for Mattes Mutual Information.
                Reduce the number of bins if a registration fails. If the number of
                bins is too large, the estimated PDFs will be a field of impulses
                and will inhibit reliable registration estimation.

                input data if there is considerable amounts of noise or the noise
                pattern in the fixed and moving images is very different.
        outputtransform: (a boolean or a file name)
                Transform calculated that aligns the fixed and moving image. Maps

                means 10mm = 1 degree. (Actual scale used is
                1/(TranslationScale^2)). This parameter is used to 'weight' or
                'standardized' the transform parameters and their effect on the

        iterations: (an integer)
                Comma separated list of iterations. Must have the same number of
                elements as the learning rate.
        learningrate: (a float)
                Comma separated list of learning rates. Learning rate is a scale
                factor on the gradient of the registration objective function
                (gradient with respect to the parameters of the transformation) used
                to update the parameters of the transformation during optimization.
                Smaller values cause the optimizer to take smaller steps through the
                parameter space. Larger values are typically used early in the
                registration process to take large jumps in parameter space followed
                by smaller values to home in on the optimum value of the
                registration objective function. Default is: 0.01, 0.005, 0.0005,
                0.0002. Must have the same number of elements as iterations.
        movingsmoothingfactor: (an integer)
                Amount of smoothing applied to moving image prior to registration.

                Transform calculated that aligns the fixed and moving image. Maps
                positions in the fixed coordinate frame to the moving coordinate
                frame. Optional (specify an output transform or an output volume or
                both).

                Number of spatial samples to use in estimating Mattes Mutual
                Information. Larger values yield more accurate PDFs and improved
                registration quality.
        terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
                Control terminal output: `stream` - displays to terminal
                immediately, `allatonce` - waits till command is finished to display
                output, `file` - writes output to file, `none` - output is ignored
        translationscale: (a float)
                Relative scale of translations to rotations, i.e. a value of 100
                means 10mm = 1 degree. (Actual scale used 1/(TranslationScale^2)).
                This parameter is used to 'weight' or 'standardized' the transform
                parameters and their effect on the registration objective function.

title: Rigid Registration

category: Legacy.Registration

description: Registers two images together using a rigid transform and mutual information.

This module was originally distributed as "Linear registration" but has been renamed to eliminate confusion with the "Affine registration" module.

This module is often used to align images of different subjects or images of the same subject from different modalities.

This module can smooth images prior to registration to mitigate noise and improve convergence. Many of the registration parameters require a working knowledge of the algorithm although the default parameters are sufficient for many registration tasks.

Inputs::

        [Mandatory]
        terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
                Control terminal output: `stream` - displays to terminal
                immediately, `allatonce` - waits till command is finished to display
                output, `file` - writes output to file, `none` - output is ignored

        [Optional]
        FixedImageFileName: (an existing file name)
                Fixed image to which to register
        MovingImageFileName: (an existing file name)
                Moving image
        args: (a string)
                Additional parameters to the command
        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
        fixedsmoothingfactor: (an integer)
                Amount of smoothing applied to fixed image prior to registration.
                Default is 0 (none). Range is 0-5 (unitless). Consider smoothing the
                input data if there is considerable amounts of noise or the noise
                pattern in the fixed and moving images is very different.
        histogrambins: (an integer)
                Number of histogram bins to use for Mattes Mutual Information.
                Reduce the number of bins if a registration fails. If the number of
                bins is too large, the estimated PDFs will be a field of impulses
                and will inhibit reliable registration estimation.
        ignore_exception: (a boolean, nipype default value: False)
                Print an error message instead of throwing an exception in case the
                interface fails to run
        initialtransform: (an existing file name)
                Initial transform for aligning the fixed and moving image. Maps
                positions in the fixed coordinate frame to positions in the moving
                coordinate frame. Optional.
        iterations: (an integer)
                Comma separated list of iterations. Must have the same number of
                elements as the learning rate.
        learningrate: (a float)
                Comma separated list of learning rates. Learning rate is a scale
                factor on the gradient of the registration objective function
                (gradient with respect to the parameters of the transformation) used
                to update the parameters of the transformation during optimization.
                Smaller values cause the optimizer to take smaller steps through the
                parameter space. Larger values are typically used early in the
                registration process to take large jumps in parameter space followed
                by smaller values to home in on the optimum value of the
                registration objective function. Default is: 0.01, 0.005, 0.0005,
                0.0002. Must have the same number of elements as iterations.
        movingsmoothingfactor: (an integer)
                Amount of smoothing applied to moving image prior to registration.
                Default is 0 (none). Range is 0-5 (unitless). Consider smoothing the
                input data if there is considerable amounts of noise or the noise
                pattern in the fixed and moving images is very different.
        outputtransform: (a boolean or a file name)
                Transform calculated that aligns the fixed and moving image. Maps
                positions in the fixed coordinate frame to the moving coordinate
                frame. Optional (specify an output transform or an output volume or
                both).
        resampledmovingfilename: (a boolean or a file name)
                Resampled moving image to the fixed image coordinate frame. Optional
                (specify an output transform or an output volume or both).
        spatialsamples: (an integer)
                Number of spatial samples to use in estimating Mattes Mutual
                Information. Larger values yield more accurate PDFs and improved
                registration quality.
        terminal_output: ('stream' or 'allatonce' or 'file' or 'none')
                Control terminal output: `stream` - displays to terminal
                immediately, `allatonce` - waits till command is finished to display
                output, `file` - writes output to file, `none` - output is ignored
        testingmode: (a boolean)
                Enable testing mode. Input transform will be used to construct
                floating image. The floating image will be ignored if passed.
        translationscale: (a float)
                Relative scale of translations to rotations, i.e. a value of 100
                means 10mm = 1 degree. (Actual scale used 1/(TranslationScale^2)).
                This parameter is used to 'weight' or 'standardized' the transform
                parameters and their effect on the registration objective function.

Outputs::

        outputtransform: (an existing file name)

                positions in the fixed coordinate frame to the moving coordinate
                frame. Optional (specify an output transform or an output volume or
                both).
