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 (multiple uses permitted) fill one or more planes on a particular image axis
• -sphere position radius value (multiple uses permitted) draw a sphere with radius in mm
• -voxel position value (multiple uses permitted) 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).
• -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.
