If you get an error that 'array' is not defined then run 'import slicer.util' and use ''. In slicer you can do this:Īnd 'a' will be a pointer to the appropriate data (no data copying). You can easily inspect and manipulate volume data using numpy and related code. You can use Tab to see lists of methods for a class instance. SampleDataLogic = SampleData.SampleDataLogic() Start Slicer and bring up python console.

Most python code can be installed and run from this window, but because it exists in the event driven Qt GUI environment, some operations like, like parallel processing or headless operation, are not easily supported. Use the Window->Python Interactor (Control-3 on window/linux, Command-3 on mac) to bring up the Qt-based console with access to the vtk, Qt, and Slicer wrapped APIs. Slicer can launch any external Python scripts (GUI is generated automatically from XML descriptor), running it by default in a background processing thread, without blocking the GUI.Slicer is accessible from Jupyter notebooks - SlicerJupyter extension makes Slicer application act as a Jupyter kernel, while keeping the application fully interactive.Python debuggers (P圜harm, VS Code, Eclipse, etc.) can attach to a running Slicer application.Any additional required python packages can be installed using pip ( pip_install('scipy'). Official, recommended way of running Python processing scripts is to execute them using Slicer's embedded Python interpreter (e.g., the Python interactor).We rather focus our efforts on other kind of Python integrations: This exists only as limited, experimental option for most other applications, too. While Slicer has a set of core libraries that could be packaged in a way so that they can be imported in any Python environment ( import slicer), but currently we don't offer this option.

Slicer is an application that embeds a Python interpreter, similarly to Blender, FreeCAD, Calibre, Cinema4D, etc. Start Here for Scripted Module and Extension DevelopmentĪn extensive tutorial and reference page was created for the Slicer/Python breakout session at the NA-MIC 2013 Summer Project Week. Slicer Self Tests can be written in python, and provide a good source of examples for manipulating the data, logic, and gui of slicer. See the python slicer4 tutorial for more examples. See this 2012 presentation on the state of python in slicer4. Topics like plotting are still experimental in slicer4.

Slicer's APIs are now natively wrapped in python. This is an evolution of the python implementation in slicer3. Look at the Script repository for examples and inspiration. Refer to this description that includes links to all the documentation.

This will give you an overall idea what is possible, and you can use a binary download of Slicer to work through the example code. Please read these slides and these slides.
