# mia-3dvf2transform(1)

Convert a 3D vectorfield from a 3D transformation.

## NAME

mia-3dvf2transform - Convert a 3D vectorfield from a 3D transformation.

## SYNOPSIS

**mia-3dvf2transform -i \<in-file\> -o \<out-file\> \[options\]**

## DESCRIPTION

**mia-3dvf2transform** Creates a 3D transformation from a vector field. The input vector field is simply encapsulated into the transformation file format. The boundary conditions and the image interpolator kernel can be set at the command line.

## OPTIONS

- \-i --in-file=(required, input); io

  input transformation \
    For supported file types see PLUGINS:3dvf/io

- \-o --out-file=(output, required); io

  output vector field \
    For supported file types see PLUGINS:3dtransform/io

- \-k --imgkernel=bspline:d=3

  image interpolator kernel which is used when the transformation is applied to an image\
    For supported plugins see PLUGINS:1d/splinekernel

- \-b --imgboundary=mirror

  Boundary condition applied when the transformation is used to transform an image\
    For supported plugins see PLUGINS:1d/splinebc

### Help & Info

- \-V --verbose=warning

  verbosity of output, print messages of given level and higher priorities. Supported priorities starting at lowest level are:

  *trace* ‐ Function call trace

  *debug* ‐ Debug output

  *info* ‐ Low level messages

  *message* ‐ Normal messages

  *warning* ‐ Warnings

  *fail* ‐ Report test failures

  *error* ‐ Report errors

  *fatal* ‐ Report only fatal errors

- \--version

  print the version number and exit

### Processing

- \--threads=-1

  Maxiumum number of threads to use for processing,This number should be lower or equal to the number of logical processor cores in the machine. (-1: automatic estimation).
