afids_utils.transforms

Methods for transforming between different coordinate systems

afids_utils.transforms.afid_world2voxel(afid_world, nii_affine)

Transform fiducials from world coordinates to voxel coordinates

Parameters:

• afid_world (numpy.ndarray[shape=(3,), dtype=numpy.float_]) – NumPy array containing floating-point spatial coordinates (x, y, z) to transform

• nii_affine (numpy.ndarray[shape=(4, 4), dtype=numpy.float_]) – NumPy array containing affine transformation associated with NifTI image

Returns:

NumPy array containing indices corresponding to voxel location along spatial dimensions

Return type:

numpy.ndarray[shape=(3,), dtype=numpy.float_]
