BrainVoyager 21.0 for Linux

BrainVoyager is our flagship product that provides a comprehensive, fast and elegant way to perform advanced neuroimaging data analysis and to create stunning visualizations. For more information, read the BrainVoyager 21 release blog post.

Installation and licensing
. BrainVoyager uses a software-based licensing system and will not run without a valid single computer or floating network license. In order to install BrainVoyager for evaluation or to update from an earlier release please use the link below:
bv_v21.0_lnx64_u16.04_installer.run (405 MB)

You can ask for a time-limited trial license to evaluate BrainVoyager with your own data. A trial license unlocks most features of a full license lacking only some optional components (no scripting and plugins). You need to accept the license agreement during installation.
Make sure that the downloaded installer file has read and executable permissions. On most modern Linux systems, this can be done by right clicking the file, selecting "Properties" (or similar) and then setting the appropriate permissions. Alternatively you can issue the following shell command (“[distro]” must be replaced with the downloaded version, e.g. “u16.04”):

> chmod 755 bv_v21.0_lnx64_[distro]_installer.run
You can now start the installation by clicking (or double-clicking) on the ".run" file from your Desktop environment or by launching the installer directly from the command line with:

> ./bv_v21.0_lnx64_[distro]_installer.run
After launching the installer, follow the instructions of the installation wizard (see image sequence on the right). In case you have an older version of BrainVoyager, close any running instance prior to installation. We also recommend to deinstall the older version of BrainVoyager by running the "uninstall" executable, which is located in the "BrainVoyager" folder. It is recommended to run the installer as a regular user (not as "root" or superuser) since this will install the program in your home directory (default: "/home/[user]/BrainVoyager" as suggested by the installer; also extensions (plugins and scripts used by the full version) will be installed in “Documents/BVExtensions” within your home directory. The installer usually places a BrainVoyager icon on the desktop (on GNOME and KDE).
If you have already a valid software license, you can continue to use BrainVoyager as before after installation and enjoy its new features. If you do not have a license, you will see a licensing screen after starting the software. To activate (unlock) a time-limited trial version, you need to send an email to “licensing [at] brainvoyager [dot] com” containing the displayed “Hardware-ID” and additional information for registration (name, institute/lab, mail address). Such an email is prepared automatically by clicking the “Prepare Email” button in the displayed "License Activation" dialog. Usually within 1-3 days you will receive a license key and a license name/ID (e.g. TSKF307BC88-PETER-SUGAR). After entering this information in the licensing dialog, the software will be activated and it is ready to use for 30 days. More details about the licensing and activation process can be found on the page BrainVoyager Software Licensing.
In order to get the full version of BrainVoyager (after evaluating the trial version), please send an email to “sales [at] brainvoyager [dot] com” to purchase a license. The full version enables some features that are disabled in the trial version, including scripting and plugins. If you purchase the full version of BrainVoyager, you will get a key that unlocks all licensed features and the software can be used as long as requested in the purchased license. There is also a floating network license available allowing to use a licensed maximum number of computers concurrently from computers in a local (e.g. lab) network. For details send an email to licensing [at] brainvoyager [dot] com.
System requirements
Version 20.6 of BrainVoyager (= v3.6 of BrainVoyager QX) is compatible with most 64 bit Linux distributions using a 3.x or newer kernel running on recent Intel/AMD machines. The provided download versions have been compiled on Ubuntu 14.04 (64 bit) but they also work on newer Ubuntu versions as well as recent versions of Red Hat Enterprise Linux (RHEL), Fedora as well as most other distributions. In case you get a "Untrusted application launcher" dialog box when launching BrainVoyager the first time from its desktop icon on Ubuntu, simply click the "Mark as Trusted" button and re-start the program. If the program does not run on your 64-bit Linux distribution, send an email to "support [at] BrainVoyager [dot] com"
Note. Since the ALT key is usually assigned to move windows on Linux, use the CTRL and SHIFT keys together when the User's Guide describes an ALT key related function (e.g. when selecting regions for the "Zoom View" panel).

While many operations of BrainVoyager run with modest working memory demands, a minimum of 2 GB is required and 4 or more GB are recommended. If you are using an NVIDIA or ATI graphics board, make sure that you install the latest accelerated OpenGL driver using the software installation tool of your distribution or by downloading the driver directly from the NVIDIA or ATI web site. Since version 20.4, BrainVoyager supports OpenCL acceleration on Linux. Downloading the latest OpenGL/OpenCL graphic card drivers will ensure best performance for hardware accelerated volume and surface rendering as well as GPU acceleration for several compute-intensive operations.
Note. OpenCL acceleration is turned off as default in the "Settings" dialog and should be turned on, if supported on your system (see topic "Exploiting the Power of GP-GPUs" in chapter "Additional Documentation" of the User's Guide).

Python Support
Since version 21, BrainVoyager for Linux supports an embedded Python interpreter as a new programming environment for scripting and plugin development. While Linux usually comes with a certain Python version (depending on the distribution), you need to install the version 3.6 of Python in the expected standard location ("/usr/bin/python3.6") in order to use Python with BrainVoyager 21. Unfortunately the Python.org website does not provide downloadable installers for Linux. One way would be to download the source and compile it on your distribution. As a more easy alternative, the PPA (personal package archive) "deadsnakes" provides a compiled version of Python 3.6 that can be installed as follows (performed on Ubuntu 16.04):

> sudo add-apt-repository ppa:deadsnakes/ppa
> sudo apt-get update
> sudo apt-get install python3.6
Since changes are made in system folders, these commands require Administrator privileges which can be obtained temporarily by prefixing the commands by "sudo", which will ask for a Administrator (login) password on first use. If the package installer "pip" is not available, it can be installed for Python 3.6 as follows:

> curl https://bootstrap.pypa.io/get-pip.py | sudo python3.6
After ensuring that the right Python (3.6) is used by "pip", core scientific computing packages can be installed that are used in BrainVoyager example Python files:

> sudo pip install numpy
> sudo pip install scipy
> sudo pip install matplotlib
Of course any other Python package can be installed in the same way. When starting BrainVoyager after Python 3.6 has been installed in the standard location ("/usr/bin/python3.6"), the Python tools (console, developer IDE) will be enabled and can be used to run and develop Python scripts and plugins. In case the tools do not work, please contact our support. When clicking the Python icon on the right side of the main toolbar, BrainVoyager presents a (docked or floating) interactive python console and a python development window that can be used to load, edit and save Python files. To learn how to use Python in BrainVoyager to script processing routines or to add new functionality, consult the Python Developer Guide that is available from the "Help" menu. You will also find several example Python files in the “Documents/BVExtensions/PythonScripts” and ”Documents/BVExtensions/PythonPlugins" folders that are accessible from the "Files" panel on the left side of the Python development window.
Documentation
The User's Guide (available locally as well as online) provides basic and advanced information about BrainVoyager and can be easily invoked by clicking the "User's Guide" icon in the main toolbar or by clicking the "User's Guide" item (or "User’s Guide (Web)" item) in the "Help" menu. The BrainVoyager 21.0 User's Guide is also available as an e-book.
Several PDF files introducing various topics are also placed in the BrainVoyager folder after installation, including the Getting Started Guide that is highly recommended for beginners. If you are upgrading BrainVoyager, you may want to check out the "News" section of the User's Guide. We highly recommend to read the release notes (see "Help" menu) to learn about new features, enhancements and bug fixes. Release notes are available for the current as well as previous releases. Documentation is also available on this web page, including the E-book version of the user's guide. If you have any questions, suggestions or bug reports, please send an email to support [at] BrainVoyager [dot] com.
