Hello everyone,  
I have a question about the mha file. I have an mha file that has a basic transform written in the file. But, I would like to change this transform with another one and save it in the file. Do you know a way to do this and even automate it afterwards? Thanks for your help.

You can [load the image file as a volume node](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#load-volume-from-file), set the IJK to RAS matrix (origin, spacing, axis directions) by calling methods on the volume node, and then [save the volume node](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#save-volume-to-file).
