Apply a colour map to an image
mrcolour [ options ] input map output
input: the input image
map: the colourmap to apply; choices are: gray,hot,cool,jet,inferno,viridis,pet,colour,rgb
output: the output image
Under typical usage, this command will receive as input ad 3D greyscale image, and output a 4D image with 3 volumes corresponding to red-green-blue components; other use cases are possible, and are described in more detail below.
By default, the command will automatically determine the maximum and minimum intensities of the input image, and use that information to set the upper and lower bounds of the applied colourmap. This behaviour can be overridden by manually specifying these bounds using the -upper and -lower options respectively.
-upper value manually set the upper intensity of the colour mapping
-lower value manually set the lower intensity of the colour mapping
-colour values set the target colour for use of the ‘colour’ map (three comma-separated floating-point values)
-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).
-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.
