= CTF electric phantom = ''Authors: Francois Tadel, Elizabeth Bock'' This tutorial explains how to use recordings from the CTF electric phantom to test dipole fitting functions. <> == Phantom description == Pictures Nature of the dipole that is generated References == 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 [[http://neuroimage.usc.edu/brainstorm3_register/download.php|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. <
