Hi all,
Could someone help to wrap itk.MultiResolutionPDEDeformableRegistration to Python? As a result, I can use multi-resolution deformable registration. Thanks in advance.
Regards,
Zhuangming Shen

Dear Zhuangming,
the [ITK Software Guide](https://itk.org/ItkSoftwareGuide.pdf) contains a section ( **9.5 Wrapping** ) devoted to explain how wrapping can be done in ITK.
Each module contains a `wrapping` folder, where the `*.warp` files are located. You can get some inspiration by reading the mentioned section and having a look at some of the existing wrap files.
You may want to read the [CONTRIBUTING](https://github.com/InsightSoftwareConsortium/ITK/blob/master/CONTRIBUTING.md) guide to submit a topic for revision, and hence, be the author of such a great contribution !
Let us know if you find difficulties.

Dear @zhuangming.shen,
a topic was submitted to gerrit for review with the wrap file of the mentioned filter:
[http://review.source.kitware.com/#/c/23203/](http://review.source.kitware.com/#/c/23203/)
Could you please test the patch set and tell us if you can use it locally with no issues?
Thanks.

Dear @jhlegarreta,
Thanks for your effort. I just downloaded the latest ITK source code from github and compiled it. I enabled ITKV3\_COMPATIBILITY, but disabled Module\_ITKv4Compatibility. After that, I still cannot run itk.MultiResolutionPDEDeformableRegistration. Did I do something wrong?
Regards,
Zhuangming Shen

Thanks for trying.
Please notice that the topic **has not been merged into `ITK master`**. In order to test the Python wrap of the class you **will need to checkout the topic** :
```auto
git fetch http://review.source.kitware.com/ITK refs/changes/03/23203/2 && git checkout FETCH_HEAD
git checkout -b AddWrappingToMultiResolutionPDEDeformableRegistration-for-release
```
Then try to use it.
Please **let us know the result of this**.

Thanks for testing @zhuangming.shen !
@fbudin @matt.mccormick does this ring a bell to you?

@zhuangming.shen Could you please try building with the `ITKV3_COMPATIBILITY` CMake option `OFF`? It should address the build error per:
