''Authors: Chinmay Chinara, Anand Joshi, Raymundo Cassani, Takfarinas Medani, David Shattuck''

BrainSuite software is a collection of image analysis tools designed to process magnetic resonance images (MRI) of the human brain. BrainSuite provides an automatic sequence to extract cortical surface mesh models from the MRI, tools to register these to a labeled atlas to define anatomical regions of interest, and tools for processing diffusion imaging data including co-registration to anatomical data, ODF and tensor fitting and tractography. BrainSuite also contains visualization tools for exploring these data, and can produce interactive maps of regional connectivity. For more details please visit https://brainsuite.org/.

  * '''BrainSuite23a_win64.exe''' (for Windows)
  * '''BrainSuite23a.dmg''' (for Mac)
  * '''BrainSuite23a.linux.tgz''' (for Linux)

== Installing MATLAB Compiler Runtime (MCR) ==
BrainSuite23a depends on '''MCR 2023a (9.14)''' which can be downloaded and installed following the steps mentioned in https://www.mathworks.com/products/compiler/matlab-runtime.html.

== Installing BrainSuite ==
Depending on the OS, the BrainSuite installation can be a bit different for each.

=== For Windows ===
 1. Launch '''BrainSuite23a_win64.exe''' that was downloaded above. You may see the security warning issue as under. Click '''More info > Run Anyway ''' to continue.<<BR>><<BR>> {{attachment:bst_warning1.png||width="300"}} {{attachment:bst_warning2.png||width="299"}}
 1. From the '''Setup''' window that pops up, click '''Yes''' if MCR 2023a has already been installed else click '''No''' and exit setup and follow steps as per the section [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Installing_MATLAB_Compile_Runtime_.28MCR.29|Installing MATLAB Compile Runtime (MCR)]] above.<<BR>><<BR>> {{attachment:bst_setup1.png||width="300"}}
 1. Follow the instructions for the Setup, indicating the folder in which you would like to save BrainSuite and its shortcuts. We recommend that you just leave it as is with the defaults and click '''Install'''.<<BR>><<BR>> {{attachment:bst_setup2.png||width="300"}}
 1. When Setup has finished, launch BrainSuite. Verify that the program has been installed correctly by checking that no red text warnings appear in the log at the bottom of the BrainSuite window.<<BR>><<BR>> {{attachment:bst_setup3.png||width="500"}}
 1. Find more details on the BrainSuite's [[https://brainsuite.org/quickstart/installation/|installation] page.

=== For Mac ===
 1. Make sure MCR 2023a has already been installed as per the section [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Installing_MATLAB_Compile_Runtime_.28MCR.29|Installing MATLAB Compile Runtime (MCR)]] above.
 1. BrainSuite for MacOS is distributed as a disk image file '''BrainSuite23a.dmg'''. To install, open BrainSuite23a.dmg and drag the '''BrainSuite23a''' folder into your '''Applications''' folder, as indicated in the pop-up window.<<BR>><<BR>> {{attachment:bst_mac1.png||width="400"}}
 1. Once the installation is completed, start BrainSuite23a from the launchpad.
 1. However, there might be security issues that might pop up as under when opening the app. This occurs due to Apple's check for certain softwares when it cannot determine if it is malicious or not. Click '''OK'''. <<BR>><<BR>> {{attachment:bst_mac2.png||width="200"}}
 1. To bypass this, instead of opening it from launchpad, use '''Finder''' to locate BrainSuite23a under '''Applications''' and open the app by '''Control and left-click > Open'''.<<BR>><<BR>> {{attachment:bst_mac3.png||width="500"}}
 1. Click '''Open''' from the pop-up that appears. BrainSuite23a is now saved as an exception to your security settings, and you can open it at any time by double-clicking it.<<BR>><<BR>> {{attachment:bst_mac4.png||width="200"}}
 1. Verify that the program has been installed correctly by checking that no red text warnings appear in the log at the bottom of the BrainSuite window.<<BR>><<BR>> {{attachment:bst_mac5.png||width="500"}}
 1. Find more details on the BrainSuite's [[https://brainsuite.org/quickstart/installation/|installation] page.

=== For Linux ===
 1. Make sure MCR 2023a has already been installed as per the section [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Installing_MATLAB_Compile_Runtime_.28MCR.29|Installing MATLAB Compile Runtime (MCR)]] above.
 1. On Linux, the software is distributed as gzipped tar file '''BrainSuite23a.linux.tgz'''. This file can be installed to whichever location is most appropriate for your system. A typical location, provided you have administrator privileges, would be '''/opt/BrainSuite23a/'''. For individual use, you may want to locate the program in your '''home''' directory.
 1. Unzip and untar '''BrainSuite23a.linux.tgz''' file. This will create a BrainSuite23a folder which includes the files for CSE, BDP, and SVReg. This can be done on the command line using:<<BR>><<BR>>'''tar xvfz BrainSuite21a.linux.tgz'''
 1. Note that you can unpack BrainSuite into the '''/opt''' directory by using:<<BR>><<BR>>'''sudo tar xvfz BrainSuite21a.linux.tgz -C /opt/'''
 1. If necessary, move the folder to its desired location. You may need to use '''sudo''' to do this.
 1. To run the GUI on Linux (requires '''glibc 2.14''', '''glibc++ 3.4.19''' or greater), launch BrainSuite23a in the bin folder from the terminal, e.g., /opt/BrainSuite23a/bin/BrainSuite23a. Doing so will launch the user interface as under. Verify that the program has been installed correctly by checking that no red text warnings appear in the log at the bottom of the BrainSuite window.<<BR>><<BR>> {{attachment:bst_linux1.png||width="500"}}

== Troubleshooting ==
=== For Windows ===
<TODO>

=== For Mac ===
==== BrainSuite not installed error ====
 1. If you get the window below while [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Testing|Testing]] above, even though you have [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Installing_MATLAB_Compiler_Runtime_.28MCR.29|installed the MCR]], this is because one of the processes in BrainSuite is not able to find the MCR 2023a location.<<BR>><<BR>> {{attachment:bst_mac_issue1.png||width="500"}}
 1. You can see the instructions how to fix this on the same Brainstorm command window as under.<<BR>><<BR>> {{attachment:bst_mac_issue2.png||width="500"}}
 1. Exit Brainstorm. Do exactly as it says, go to '''/Applications/BrainSuite23a/bdp/bdp.sh''' and edit the line highlighted as under i.e. set '''BrainSuiteMCR="/Applications/MATLAB/MATLAB_Runtime/R2023a";'''<<BR>><<BR>> {{attachment:bst_mac_issue3.png||width="500"}}
 1. Save and exit the file. Rerun the [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Testing|Testing]]. You might have things run successfully else another error might pop up related to security as described below.

==== "bdp" is malicious security warning ====
 1. You might see the following window. This occurs due to Apple's check for certain softwares when it cannot determine if it is malicious or not. Click '''OK''' and '''OK''' again in the Brainstorm error window that pops up. <<BR>><<BR>> {{attachment:bst_mac_issue4.png||width="200"}}
 1. To bypass this, use '''Finder''' to locate '''bdp''' under '''/Applications/Brainsuite23a/bdp/bdp''' and open the app by '''Control and left-click > Open'''.<<BR>><<BR>> {{attachment:bst_mac_issue5.png||width="400"}}
 1. Click '''Open''' from the pop-up that appears. '''bdp''' is now saved as an exception to your security settings.<<BR>><<BR>> {{attachment:bst_mac_issue6.png||width="200"}}
 1. Rerun the [[https://neuroimage.usc.edu/brainstorm/Tutorials/BstBrainSuite#Testing|Testing]] and everything should work normally now.
