# warpcorrect¶

## Synopsis¶

Replaces voxels in a deformation field that point to a specific out of bounds location with nan,nan,nan

## Usage¶

warpcorrect [ options ]  in out

• in: the input warp image.
• out: the output warp image.

## Description¶

This can be used in conjunction with the warpinit command to compute a MRtrix compatible deformation field from non-linear transformations generated by any other registration package.

## Options¶

• -marker coordinates single value or a comma separated list of values that define out of bounds voxels in the input warp image. Default: (0,0,0).
• -tolerance value numerical precision used for L2 matrix norm comparison. Default: 9.99999975e-06.

### 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).
