labelsgmfix
===========

Synopsis
--------

In a FreeSurfer parcellation image, replace the sub-cortical grey matter structure delineations using FSL FIRST

Usage
--------

::

    labelsgmfix parc t1 lut output [ options ]

-  *parc*: The input FreeSurfer parcellation image
-  *t1*: The T1 image to be provided to FIRST
-  *lut*: The lookup table file that the parcellated image is based on
-  *output*: The output parcellation image

Options
-------

Options for the labelsgmfix script
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- **-premasked** Indicate that brain masking has been applied to the T1 input image

- **-sgm_amyg_hipp** Consider the amygdalae and hippocampi as sub-cortical grey matter structures, and also replace their estimates with those from FIRST

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

- **-info** Display additional information and progress for every command invoked

- **-debug** Display additional debugging information over and above the output of -info
