# antsAffineInitializer(1)

part of ANTS registration suite

## NAME

antsAffineInitializer - part of ANTS registration suite

## SYNOPSIS

**antsAffineInitializer** *ImageDimension \<Image1.ext\> \<Image2.ext\> TransformOutput.mat Optional-SearchFactor Optional-Radian-Fraction Optional-bool-UsePrincipalAxes Optional-uint-UseLocalSearch Optional-Image1Mask*

## DESCRIPTION

-

  Optional-SearchFactor is in degrees **---** e.g. 10 = search in 10 degree increments . Radian-Fraction should be between 0 and 1 **---** will search this arc +/- around principal axis. Optional-bool-UsePrincipalAxes determines whether the rotation is searched around an initial principal axis alignment.  Default = false. Optional-uint-UseLocalSearch determines if a local optimization is run at each search point for the set number of iterations. Default = 20.
