Computes a dissimilarity metric between two images
mrmetric [ options ] image1 image2
- image1: the first input image.
- image2: the second input image.
Currently only the mean squared difference is implemented.
- -space iteration method voxel (default): per voxel image1: scanner space of image 1 image2: scanner space of image 2 average: scanner space of the average affine transformation of image 1 and 2
- -interp method set the interpolation method to use when reslicing (choices: nearest, linear, cubic, sinc. Default: linear).
- -metric method define the dissimilarity metric used to calculate the cost. Choices: diff (squared differences), cc (negative cross correlation). Default: diff). cc is only implemented for -space average and -interp linear.
- -mask1 image mask for image 1
- -mask2 image mask for image 2
- -nonormalisation do not normalise the dissimilarity metric to the number of voxels.
- -overlap output number of voxels that were used.
- -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.
