itk_convert_xfm

convert transformation files between ITK and MINC .xfm formats

itk_convert_xfm <input> <output> [options]

DESCRIPTION

itk_convert_xfm converts spatial transformation files between MINC .xfm format and ITK transformation formats. This allows transformations computed by ITK-based registration tools (such as ANTs) to be used with MINC tools, and vice versa.

The conversion direction is determined automatically from the file extensions of the input and output arguments. The tool handles both linear (affine) and non-linear (grid/deformation field) transformations.

The --invert option inverts the transformation during conversion, which is useful when the source and target conventions differ between toolkits.

OPTIONS

--verbose

Print verbose information during processing.

--clobber

Overwrite the output file if it already exists.

--invert

Invert the transformation during conversion.

EXAMPLES

Convert a MINC .xfm file to ITK format:

itk_convert_xfm input.xfm output.txt

Convert an ITK transform to MINC .xfm format:

itk_convert_xfm input.txt output.xfm --clobber

Convert and invert a transformation:

itk_convert_xfm input.xfm output.txt --invert --verbose
