Hi  
I got a runtime error related to this:

```
`the method itk::ProcessObject::SetInput was part of the deprecated API.`

```

Where can change to make it works? nothing related is mentioned [here] ([https://itk.org/Wiki/ITK/Release\_4/Removed\_or\_renamed\_classes](https://itk.org/Wiki/ITK/Release_4/Removed_or_renamed_classes))

Thanks!

Hi Ibraheem,

I good place to look for migration guidance is the [ITK v4 Migration](https://itk.org/migrationv4/) website.

However, it is unclear what is being migrated. Is there a full stack trace for the error?

Thanks,  
Matt
