5ttgen freesurfer

Synopsis

5ttgen freesurfer [ options ] input output
  • input: The input FreeSurfer parcellation image (any image containing ‘aseg’ in its name)
  • output: The output 5TT image

Description

Generate the 5TT image based on a FreeSurfer parcellation image

Options

Options specific to the ‘freesurfer’ algorithm

  • -lut Manually provide path to the lookup table on which the input parcellation image is based (e.g. FreeSurferColorLUT.txt)

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

Standard options

  • -continue <TempDir> <LastFile> Continue the script from a previous execution; must provide the temporary directory path, and the name of the last successfully-generated file
  • -force Force overwrite of output files if pre-existing
  • -help Display help information for the script
  • -nocleanup Do not delete temporary files during script, or temporary directory at script completion
  • -nthreads number Use this number of threads in MRtrix multi-threaded applications (0 disables multi-threading)
  • -tempdir /path/to/tmp/ Manually specify the path in which to generate the temporary directory
  • -quiet Suppress all console output during script execution
  • -verbose Display additional information for every command invoked

5ttgen fsl

Synopsis

5ttgen fsl [ options ] input output
  • input: The input T1-weighted image
  • output: The output 5TT image

Description

Use FSL commands to generate the 5TT image based on a T1-weighted image

Options

Options specific to the ‘fsl’ algorithm

  • -t2 <T2 image> Provide a T2-weighted image in addition to the default T1-weighted image; this will be used as a second input to FSL FAST
  • -mask Manually provide a brain mask, rather than deriving one in the script
  • -premasked Indicate that brain masking has already been applied to the input image

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

Standard options

  • -continue <TempDir> <LastFile> Continue the script from a previous execution; must provide the temporary directory path, and the name of the last successfully-generated file
  • -force Force overwrite of output files if pre-existing
  • -help Display help information for the script
  • -nocleanup Do not delete temporary files during script, or temporary directory at script completion
  • -nthreads number Use this number of threads in MRtrix multi-threaded applications (0 disables multi-threading)
  • -tempdir /path/to/tmp/ Manually specify the path in which to generate the temporary directory
  • -quiet Suppress all console output during script execution
  • -verbose Display additional information for every command invoked
