Use CMTK mat2dof to convert homogeneous affine matrix into CMTK registration

Use CMTK mat2dof to convert homogeneous affine matrix into CMTK registration

cmtk.mat2dof(m, f = NULL, centre = NULL, Transpose = TRUE, version = FALSE)

Arguments

m

Homogenous affine matrix (4x4) last row 0 0 0 1 etc

f

Output file (optional)

centre

Centre for rotation (optional 3-vector)

Transpose

the input matrix so that it is read in as it appears on disk

version

When TRUE, function returns CMTK version number of mat2dof tool

Value

5x3 matrix of CMTK registration parameters or logical

Details

If no output file is supplied, 5x3 params matrix will be returned directly. Otherwise a logical will be returned indicating success or failure at writing to disk.

Transpose is true by default since this results in an R matrix with the transpose in the fourth column being correctly interpreted by cmtk.
