Installation & Updates

Brainstorm is available in two distinct forms, both available for Windows, Linux and MacOSX:

• An open-source Matlab application (Matlab required)

  • Necessary: Matlab version R2006a (7.2), or later

  • Optional: Signal Processing Toolbox (for frequency filtering and resampling)
• A stand-alone Java executable (Matlab not required)
  • Requires the free download of the Matlab runtime library (MCR)

  • MacOS: MacOSX version >= 10.6.4 (Snow Leopard), with Apple Java installed (see link)

Working with MEG/EEG recordings involves a lot of computational resources and large display windows. Therefore we recommand that you use a computer with a decent processing capacity and a screen larger than 13".

You would also add to your comfort by using an external mouse instead of your laptop pad. Most of the manipulations are done with the mouse, and some involve an intensive use of the scrolling operation. A mouse wheel or the "two-finger move" on MacBooks are perfect for this, but this operation is not always easy to perform on some laptops.

Installation

1. Go to the Download page, complete the quick and free registration process
   (it helps us keep track of our users' demographics)

2. Download the latest brainstorm_....zip archive

3. Unzip it somewhere on your computer, for example:
   

   • Windows: Program Files\brainstorm3

   • Linux: /usr/local/brainstorm3 (or ~/brainstorm3 if you are not admin)

   • MacOS: Applications/brainstorm3

4. Create a new folder named e.g., "brainstorm_db", which will be used by the Brainstorm database. For example:

   • Windows: My documents\brainstorm_db

   • Linux: /home/username/brainstorm_db

   • MacOS: Documents/brainstorm_db

Start Brainstorm

With Matlab

1. Start Matlab

2. Do NOT add brainstorm3 folder to your path: this will be done automatically

3. Go to the brainstorm3 folder
4. Type "brainstorm" in the command window
5. When asked for the location of the Brainstorm database folder, pick the folder "brainstorm_db" you have just created

6. We recommend you visit the Tutorials pages to learn how to use most features of the software.

Without Matlab

1. Download the Matlab Compiler Runtime (MCR) corresponding to your operating system. This is a set of libraries that will let you run Brainstorm on your computer without Matlab.
   Click here: Link to the Mathworks website.

2. Install the MCR:

   • Windows: Double-click on the .exe and follow the instructions

   • Linux: From a terminal, unzip .zip, then run ./install

   • MacOS: Click on the zip file to unzip it, then click on "InstallForMacOSX".
     It is not clear on the Mathworks website, but the current MCR requires a version of
     MacOSX 10.6.4 (Snow Leopard), with Apple Java installed (see link).
     If you can't install the MCR on your Mac, you can chose between: updating MacOS or installing Matlab.

3. Run the program in brainstorm3/bin/R2012b/

   • Windows: Double-click on brainstorm3.bat

   • Linux: From a terminal, cd brainstorm3/bin/R2012b/

     • Make sure that the file "brainstorm.command" is executable:
       => chmod a+x brainstorm.command

     • run ./brainstorm.command

   • MacOS: Double-click on brainstorm.command

4. When you start Brainstorm for the first time on Linux or MacOS, you will be prompted to select the folder where you installed the MCR
5. When asked for the location of the Brainstorm database folder, pick the folder "brainstorm_db" you have just created

6. Visit the Tutorials section to learn how to use most features of the software.

Updates

Brainstorm is quickly improving and evolving. We have chosen not to go through a stable-release policy but rather, we established a quick and easy way to update the software seamlessly for you. Although this approach has its shares of risks of possibly seeing new bugs emerging from the most recent update, it has the great advantage of being dynamic and of rapidly disseminating new, important features. We encourage our users to report bugs through our forum, and our experience shows fixes are completed quickly enough to avoid disruptive downtime to our users.

For these reasons, we recommend that you update Brainstorm regularly using the following options:

• Automatic updates (Matlab version only):
  • When Brainstorm starts, it automatically checks online if a version newer than a month-old is available.

  • To disable the automatic updates, edit the software preferences accordingly (File > Set preferences...)

  • Restart Matlab after updating the software.
• Manual updates (Matlab version only):

  • Menu Help > Update Brainstorm, in the main application window.

  • If it doesn't work: check that you have the rights to write in the brainstorm3 folder.
  • Restart Matlab after updating the software.
• Stand-alone version (or in case the above methods do not work for you)
  • Delete the brainstorm3 folder (it will not delete your database)
  • Dowload the latest release of the Brainstorm executable or its Matlab version
  • Follow the installation instructions (see above)
