eddymotion.registration.ants module

Using ANTs for image registration.

eddymotion.registration.ants.generate_command(fixed_path: str | Path, moving_path: str | Path, fixedmask_path: str | Path | list[str] | None = None, movingmask_path: str | Path | list[str] | None = None, init_affine: str | Path | None = None, default: str = 'b0-to-b0_level0', **kwargs: dict) → str[source]

Generate an ANTs’ command line.

Parameters:

  • fixed_path (os.pathlike) – Path to the fixed image.

  • moving_path (os.pathlike) – Path to the moving image.

  • fixedmask_path (os.pathlike or list, optional) – Path to the fixed image mask.

  • movingmask_path (os.pathlike or list, optional) – Path to the moving image mask.

  • init_affine (os.pathlike, optional) – Initial affine transformation.

  • default (str, optional) – Default settings configuration.

  • **kwargs (dict) – Additional parameters for ANTs registration.

Returns:

The ANTs registration command line string.

Return type:

str
