**What it does**

<![CDATA[
Calculates the warping index of two elastic transformations, i.e. the average of the geometrical distance
between every pixel and its version after applying both transformations (direct and inverse). This value
is given as a result. The transformation files must be in the same format format as the files created with
the **Save Transformation** option in the **Align two images with bUnwarpJ** tool.
