c_param2grid

Convert cylindrical harmonic parameters to deformation grid.

c_param2grid <parameters> <output_grid.mnc> [options]

DESCRIPTION

c_param2grid converts a cylindrical harmonic parameter file (produced by c_fit_harmonics_grids) into a MINC deformation grid volume. The resulting grid represents the distortion correction field that can be applied to images using tools such as mincresample or itk_resample.

A reference MINC file can be provided with --like to define the sampling grid geometry (dimensions, voxel size, and orientation). Alternatively, a uniform step size can be specified.

OPTIONS

--verbose

Print progress information during processing.

--clobber

Overwrite the output file if it already exists.

--like file

Use the specified MINC file as a template for the output grid geometry.

--step val

Set the voxel step size (in mm) for the output grid.

--cylindrical

Interpret parameters as cylindrical harmonics.

EXAMPLES

# Convert parameters to a grid using a reference volume
c_param2grid distortion.par correction_grid.mnc --like reference.mnc

# Convert with a specified step size
c_param2grid distortion.par correction_grid.mnc --step 2.0
