mrstats

Synopsis

Compute images statistics

Usage

mrstats [ options ]  image
  • image: the input image from which statistics will be computed.

Options

Statistics options

  • -output field (multiple uses permitted) output only the field specified. Multiple such options can be supplied if required. Choices are: mean, median, std, std_rv, min, max, count. Useful for use in scripts. Both std options refer to the unbiased (sample) standard deviation. For complex data, min, max and std are calculated separately for real and imaginary parts, std_rv is based on the real valued variance (equals sqrt of sum of variances of imaginary and real parts).
  • -mask image only perform computation within the specified binary mask image.
  • -ignorezero ignore zero values during statistics calculation

Additional options for mrstats

  • -allvolumes generate statistics across all image volumes, rather than one set of statistics per image volume

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).
  • -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.
