       THIS TOOL IS DEPRECATED. PLEASE USE streamxform INSTEAD.

       This  tool  reads  a  list  of  3D  coordinates  and  applies  a  coordimnate transformation to them. The
       transformation can optionally be inverted. The transformed  coordinates  are  then  written  to  standard
       output.

GlobalToolkitOptions(thesearesharedbyallCMTKtools)--help
            Write list of basic command line options to standard output.

       --help-all
            Write complete list of basic and advanced command line options to standard output.

       --wiki
            Write list of command line options to standard output in MediaWiki markup.

       --man
            Write man page source in 'nroff' markup to standard output.

       --version
            Write toolkit version to standard output.

       --echo
            Write the current command line to standard output.

       --verbose-level<integer>
            Set verbosity level.

       --verbose, -v
            Increment verbosity level by 1 (deprecated; supported for backward compatibility).

       --threads<integer>
            Set maximum number of parallel threads (for POSIX threads and OpenMP).

   MainOptions--accuracy<double>, -a<double>
            Approximation accuracy (maximum error) [Default:0.01]--no-check, -x
            Disable accuracy checking and always output something

       --forward, -f
            Apply forward transformation (default: backward)

       --fallback-inverse<string>, -F<string>
            Fallback inverse transformation (used for initialization and in case of failure) [Default:NONE]--input-file<string>, -i<string>
            Input path [default: STDIN].  [Default:NONE]--output-file<string>, -o<string>
            Output path [default: STDOUT].  [Default:NONE]--affine, -n
            Apply affine transformation even if warp studylist specified

       --binary, -b
            Read Binary input and produce binary output (floats)

       --jacobian, -j
            Calculate  jacobian  determinant  rather  than  mapping point (default: false)
                 NB: JDet is >1 if the sample volume is larger than the reference

       --normalised-jacobian, -J
            Calculate jacobian determinant normalised by global scaling factor (default: false)

       --return-global-scaling, -g
            Return global scaling factor ie the scaling due to initial affine
