I want to open my custom scripted module every time I open Slicer.
I know that I have to edit the .slicerrc.py file, but I don’t know what lines of code to put in there.

As an example I add this to the command line when I start slicer:
```auto
--python-code "selectModule('WebServer')"
```
But you can put the same in `.slicerrc.py`, maybe using `slicer.util.selectModule` for style purposes.

The Slicer script repository has many python examples that may be helpful for you. One includes setting the slicer module for startup.

Using the GUI, you can go to Settings-\>Modules and set the Default startup module from the list of loaded modules. Here I have set “OpenIGTLinkIF” as my new default.
