"""
A Nipype workflow to perform image registration between two templates
*R* and *M*. *R* is the *reference template*, selected by a templateflow
identifier such as ``MNI152NLin2009cAsym``, and *M* is the *moving
template* (e.g., ``MNI152Lin``). This workflows maps data defined on
template-*M* space onto template-*R* space.
1. Run the subrogate images through ``antsBrainExtraction``.
2. Recompute :abbr:`INU (intensity non-uniformity)` correction using
the mask obtained in 1).
3. Independently, run spatial normalization of every
:abbr:`INU (intensity non-uniformity)` corrected image
(supplied via ``in_files``) to both templates.
4. Calculate an initialization between both templates, using them directly.
5. Run multi-channel image registration of the images resulting from
3). Both sets of images (one registered to *R* and another to *M*)
are then used as reference and moving images in the registration
framework.
**Parameters**
in_files: list of files
a list of paths pointing to the images that will be used as surrogates
mov_template: str
a templateflow identifier for template-*M*
ref_template: str
a templateflow identifier for template-*R* (default: ``MNI152NLin2009cAsym``).
