Hi -

A couple suggestions:

- you can update to use the Segment Editor (in the latest release) and use it in place of the Editor and ModelMaker steps. ([https://www.slicer.org/wiki/Documentation/4.10/Training#Segmentation](https://www.slicer.org/wiki/Documentation/4.10/Training#Segmentation))

- to automate things in Slicer you can use python scripting, which is very powerful and not too hard to learn ([https://www.slicer.org/wiki/Documentation/Nightly/Developers/Python\_scripting](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Python_scripting))

As for the extension catalog it should be available. Maybe these links will help you debug.

Hope that helps.
