2013 Project Week Breakout Session:Slicer4Python

Back to Summer project week Agenda

Goals

The material here provides a guided walk through of the resources available for python scripting in Slicer 4. It is based on what is available in the nightly builds as of project week (June 17, 2013). One goal is to demonstrate the development of a python scripted slicer module. Another goal is to provide "A Guide to Python in Slicer for the Casual Power User" which means that this walkthrough of the features of slicer should give you an idea how to make a custom module that helps organize and automate your processing. This can be useful for your own research or you can create helper modules that simplify the work for users who are exploring an algorithm or working with a large set of studies.

Topics

Creating a scripted module from templates with ModuleWizard

This topic is covered in | the ModuleWizard documentation. It allows you to create a skeleton extension with any combination of modules you want.

Prerequisites

We'll go through the steps on a Mac, but the steps are essentially the same on all platforms. We'll be using a locally built version of slicer created using these instructions, but the steps can also be performed using a binary download as long as you have a checkout of the slicer source code available.

Make an extension framework

For this example we'll make an extension with a single scripted module as a demonstration. We run the following command from the Slicer source directory.

./Utilities/Scripts/ModuleWizard.py --template ./Extensions/Testing/ScriptedLoadableExtensionTemplate --target ../MyExtension MyExtension
