warpinvert

Synopsis

Invert a non-linear warp field

Usage

warpinvert [ options ]  in out
  • in: the input warp image.
  • out: the output warp image.

Description

By default, this command assumes that the input warp field is a deformation field, i.e. each voxel stores the corresponding position in the other image (in scanner space), and the calculated output warp image will also be a deformation field. If the input warp field is instead a displacment field, i.e. where each voxel stores an offset from which to sample the other image (but still in scanner space), then the -displacement option should be used; the output warp field will additionally be calculated as a displacement field in this case.

Options

  • -template image define a template image grid for the output warp
  • -displacement indicates that the input warp field is a displacement field; the output will also be a displacement field

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.
