No option to load parameter file from memory

[ViktorvdValk]

It is not possible to load a transform parameter file directly from memory, the file has to be save to a .txt file first before it can be read and given to elastix. See example notebook 11.

Has this been fixed over the last 3 years?

Thanks for asking, @dzenanz, I think the answer is yes 😄

With ElastixRegistrationMethod::SetInitialTransformParameterObject, added earlier this year by:

• pull request Add SetInitialTransformParameterObject to ElastixRegistrationMethod SuperElastix/elastix#856
• commit SuperElastix/elastix@48c6458
• Included with ITKElastix by pull request Bump elastix version to 2023-05-15, use C++17, support any scalar pixel type #211

(TransformixFilter has a similar member function, SetTransformParameterObject, for a few years already.)

A ParameterObject basically has the content of a parameter file in memory.
