It can be created from Lead-DBS and an example dataset is already included in the SlicerNetstim extension. ## Loading sample ORScene A sample ORScene is included to test the platform. To load it follow the next steps: 1. Open Slicer. 2. Switch to Sample Data module. 3. Scroll down and select STN Planning. See the following screenshots as reference:

Step 2: Switch to Sample Data module.

Step 3: Select STN Planning ORScene.

## Creating new ORScene In order to create an ORScene follow the next steps: 1. Process a subject in Lead-DBS with the **co-registration** and **normalization** steps. 2. Place the surgical planning files under a `leador` subfolder within the subject folder. 3. Load the subject in Lead-DBS and select `Tools > Lead-OR > Create ORScene`. Note that the selected atlas will be put into the scene as well. 4. Drag and drop the `ORScene.mrb` file into Slicer. See the following screenshots as reference.

Step 2: Lead-DBS subject processed and with Brainlab planning files in respective folder.

Step 3: Create ORScene from Lead-DBS.

Step 4: Output folder with file to load into Slicer.
