.. _tckconvert: tckconvert =================== Synopsis -------- Convert between different track file formats Usage -------- :: tckconvert [ options ] input output - *input*: the input track file. - *output*: the output track file. Description ----------- The program currently supports MRtrix .tck files (input/output), ascii text files (input/output), VTK polydata files (input/output), and RenderMan RIB (export only). Note that ascii files will be stored with one streamline per numbered file. To support this, the command will use the multi-file numbering syntax, where square brackets denote the position of the numbering for the files, for example: $ tckconvert input.tck output-'[]'.txt will produce files named output-0000.txt, output-0001.txt, output-0002.txt, ... Options ------- - **-scanner2voxel reference** if specified, the properties of this image will be used to convert track point positions from real (scanner) coordinates into voxel coordinates. - **-scanner2image reference** if specified, the properties of this image will be used to convert track point positions from real (scanner) coordinates into image coordinates (in mm). - **-voxel2scanner reference** if specified, the properties of this image will be used to convert track point positions from voxel coordinates into real (scanner) coordinates. - **-image2scanner reference** if specified, the properties of this image will be used to convert track point positions from image coordinates (in mm) into real (scanner) coordinates. Options specific to PLY writer ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - **-sides sides** number of sides for streamlines - **-increment increment** generate streamline points at every (increment) points Options specific to RIB writer ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - **-dec** add DEC as a primvar Options for both PLY and RIB writer ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - **-radius radius** radius of the streamlines Options specific to VTK writer ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - **-ascii** write an ASCII VTK file (binary by default) Standard options ^^^^^^^^^^^^^^^^ - **-info** display information messages. - **-quiet** do not display information messages or progress status; alternatively, this can be achieved by setting the MRTRIX_QUIET environment variable to a non-empty string. - **-debug** display debugging messages. - **-force** force overwrite of output files (caution: using the same file as input and output might cause unexpected behaviour). - **-nthreads number** use this number of threads in multi-threaded applications (set to 0 to disable multi-threading). - **-config key value** *(multiple uses permitted)* temporarily set the value of an MRtrix config file entry. - **-help** display this information page and exit. - **-version** display version information and exit.
