【MRtrix】MRtrixを用いた5TT（five-tissue-type）画像の生成

SYNOPSIS

     Generate a 5TT image suitable for ACT

USAGE

     5ttgen [ options ] algorithm ...

        algorithm    Select the algorithm to be used to complete the script operation;
                     additional details and options become available once an
                     algorithm is nominated. Options are: freesurfer, fsl, gif,
                     hsvs

DESCRIPTION

     5ttgen acts as a 'master' script for generating a five-tissue-type (5TT)
     segmented tissue image suitable for use in Anatomically-Constrained
     Tractography (ACT). A range of different algorithms are available for
     completing this task. When using this script, the name of the algorithm to
     be used must appear as the first argument on the command-line after
     '5ttgen'. The subsequent compulsory arguments and options available depend
     on the particular algorithm being invoked.

     Each algorithm available also has its own help page, including necessary
     references; e.g. to see the help page of the 'fsl' algorithm, type '5ttgen
     fsl'.

Options common to all 5ttgen algorithms

  -nocrop
     Do NOT crop the resulting 5TT image to reduce its size (keep the same
     dimensions as the input image)

  -sgm_amyg_hipp
     Represent the amygdalae and hippocampi as sub-cortical grey matter in the
     5TT image

Additional standard options for Python scripts

  -nocleanup
     do not delete intermediate files during script execution, and do not delete
     scratch directory at script completion.

  -scratch /path/to/scratch/
     manually specify the path in which to generate the scratch directory.

  -continue <ScratchDir> <LastFile>
     continue the script from a previous execution; must provide the scratch
     directory path, and the name of the last successfully-generated file.

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.

  -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.
