Installation and updates

Brainstorm is available in two forms: an open-source Matlab application (Matlab license required) and a standalone Java executable (free). Both are available for download in the same package.

Requirements

With Matlab

• Matlab >= R2009b (7.9)

• Optional toolboxes: Signal Processing, Parallel Processing

• For smoother graphics, we recommend Matlab >= R2014b:
  
  

Without Matlab

• Matlab Runtime: R2020a (9.8)

  • Download for free from the Mathworks website

  • Supported operating systems: Windows, Linux, MacOS

• If your OS is not supported, Brainstorm is available for older versions of the Matlab Runtime:

  • Recommend version: 2015b

  • See all the versions available at the bottom of the Download page

Hardware recommendations

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

• Mouse: 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.

• Memory: Brainstorm can work with a limited amount of memory, it will only restrict the loading of larger files. However, you are strongly advised to work with a 64bit operating system. Computers running a Windows 32bit system may run into a lot of "Out of memory" errors.

Installation

1. Go to the Download page, complete the quick and free registration process.

2. If you don't receive the confirmation email, please check your spam folder.

3. Download one of the lastest archive:

   • Source: brainstorm_yymmdd_src.zip - For execution within Matlab

   • Binary: brainstorm_yymmdd_bin.zip - Compiled version with no Matlab license required

   • Source + binary: brainstorm_yymmdd.zip - Everything in the same zip file

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

   • Windows: My documents\brainstorm3

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

   • MacOS: Applications/brainstorm3

5. Create a new folder "brainstorm_db" for the Brainstorm database, for example:

   • Windows: My documents\brainstorm_db

   • Linux: /home/username/brainstorm_db

   • MacOS: Documents/brainstorm_db

   • Warning: Never create this folder inside the program folder (brainstorm3), it would get deleted when updating Brainstorm.

6. Set up a regular backup for your brainstorm_db folder, like you would do for any work you do on your computer. Losing hundreds of hours of work because of a wrong manipulation or a disk failure is common, but easy to avoid.

Start Brainstorm

With Matlab

1. Start Matlab

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

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

6. Follow all the introduction tutorials in the section "Get started": Tutorials

Without Matlab

1. Download the Runtime R2020a (9.8) for your operating system: Mathworks website

2. Install the Matlab Runtime:

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

   • MacOS: Click on the zip file to unzip it, then click on "InstallForMacOSX"

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

3. Run the program in brainstorm3/bin/R2020a/

   • Windows: Double-click on brainstorm3.bat

   • MacOS: Double-click on brainstorm3.command and wait for instructions

   • Linux: From a terminal, run:
     cd brainstorm3/bin/R2020a/
     ./brainstorm3.command

4. Troubleshooting for MacOS or Linux:

   • On recent versions of MacOS, you may get an error message "Application can't be opened because it is from an unidentified developer". This message would appear for all the programs that were not downloaded from the Apple app-store. To go around this verification: right-click on the application > Open, then click on the Open button.

   • Other MacOS issues are discussed on the forum: Support for MacOS BigSur.

   • Some Linux Mint users have reported having interface issues, changing the graphical theme of their OS fixed this problem.

   • From a terminal, make sure that the file "brainstorm3.command" is executable:
     chmod a+x brainstorm3.command

   • If nothing happens, run:
     ./brainstorm3.command MCR_DIR
     MCR_DIR being the MCR 9.8 folder (ex: /Applications/MATLAB/MCR/v98)

   • Try with another binary release: See at the bottom of the Download page

5. Troubleshooting for Windows:

   • Your current user may not have the necessary privileges. If are an administrator for your computer, you can do the following: right-click on brainstorm3.bat > Run as administrator.

   • If you are not the administrator of your computer and Matlab or the Runtime are not installed in the standard paths, Brainstorm may have trouble finding them. To specify manually the path of the Runtime or Matlab folder, right-click on brainstorm3.bat > Edit. Fill the second line of the script (Example: @SET MATLABROOT="C:\Program Files\MATLAB\R2020a"), save the file, and try to execute it again.

6. On Linux or MacOS, you may be asked to select the folder where you installed the Runtime.
7. When asked for the Brainstorm database folder, pick the "brainstorm_db" you have just created.

8. Follow all the introduction tutorials in the section "Get started": Tutorials

Managing emails

After creating a new account, you will start receiving by email a weekly digest of the activity on the Brainstorm forum: questions from users, methodological discussions and bug reports.

If you would like to stop receiving these emails, log into the forum, go to your email preferences, and disable the option "When I don’t visit here, send me an email summary of popular topics and replies".

If instead you would like to receive a copy of all the messages posted on the forum, select the option "Enable mailing list mode".

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 checks online if a version newer than a month-old is available.

  • To disable the automatic updates, edit the software preferences (File > Edit 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.
• Standalone version (or in case the above methods do not work for you)
  • Delete the brainstorm3 folder (it will not delete your database, which is in your user folder)
  • Download the latest release of Brainstorm
  • Follow the installation instructions (see above)
