Download and installation

• Requirements: You have already followed all the introduction tutorials and you have a working copy of Brainstorm installed on your computer.

• Go to the Download page of this website, and download the file: sample_phantom.zip

• Unzip it in a folder that is not in any of the Brainstorm folders (program folder or database folder)
• Start Brainstorm (Matlab scripts or stand-alone version)

• Select the menu File > Create new protocol. Name it "TutorialPhantom" and select the options:

  • "No, use individual anatomy",

  • "No, use one channel file per acquisition run (MEG)".

Generate anatomy

• In the Matlab command window: type "generate_ctf_phantom".

• This creates a new subject Phantom and generates the "anatomy" for this device: one volume and a few surfaces representing the geometry of the phantom.
  
  

• You can display the MRI and surfaces as presented in the introduction tutorials.
