mredit
===================

Synopsis
--------

Directly edit the intensities within an image from the command-line

Usage
--------

::

    mredit [ options ]  input[ output ]

-  *input*: the input image
-  *output*: the (optional) output image

Description
-----------

A range of options are provided to enable direct editing of voxel intensities based on voxel / real-space coordinates. If only one image path is provided, the image will be edited in-place (use at own risk); if input and output image paths are provided, the output will contain the edited image, and the original image will not be modified in any way.

Options
-------

-  **-plane axis coord value** fill one or more planes on a particular image axis

-  **-sphere position radius value** draw a sphere with radius in mm

-  **-voxel position value** change the image value within a single voxel

-  **-scanner** indicate that coordinates are specified in scanner space, rather than as voxel coordinates

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).

-  **-help** display this information page and exit.

-  **-version** display version information and exit.
