Release of BrainVoyager 3.9

The latest version of BrainVoyager was sent to customers during the last two weeks. If you are a customer of BrainVoyager and you did not receive a copy automatically, please send us an email immediately. BrainVoyager now comes with a help file describing many of the new features. You can also access the updated help directly from our web site.

Exhibition at HBM'99

Do you want to see the future of BrainVoyager? Then visit us at booth #19 at the Human Brain Mapping conference in Düsseldorf. We will present the first beta of the upcoming BrainVoyager 4.0 / 2000. The new version - scheduled to be released in late August - contains a number of important new developments including surface-based statistical data analysis efficiently addressing the multiple comparison problem and surface-based inter-subject anatomical alignment going beyond Talairach-based functional data averaging. Another important aspect of the upcoming version is that BrainVoyager has been redesigned to provide a fully open architecture. This was possible through implementation of soc called dual COM interfaces which allow efficient access to most methods and properties of BrainVoyager. The first application of the new open architecture is scripting and automation: write simple VisualBasic, Java or Perl scripts to fully control BrainVoyager acting as a server application. We use the scripting ability now to program scripts demonstrating the main features of BrainVoyager. The biggest advantage of scripting is, of course, that you can analyze multiple data sets in batch mode. Scripts can be also exchanged between users of BrainVoyager.
BrainVoyager goes Unix. At HBM, we will also present the first prototype of the Unix version of BrainVoyager scheduled to be available end of this year. The Unix version will have an almost identical user interface as the Windows version. This is possible since the Unix version is programmed using the Qt library from Troll Tech, the same library which is used by the KDE development team. The Unix BrainVoyager will be available under all derivates supported by Qt (including LInux, Sun Solaris and SGI Irix).
StimulDX. With BrainVoyager 2000 we will also offer a new module called StimulDX for the flexible design of stimulation paradigms. StimulDX may be called from BrainVoyager to select /define visual and auditory experiments. Since StimulDX "tells" BrainVoyager how the experiments are designed, BrainVoyager will automatically create appropriate stimulation protocol files as well as project files from the raw imaging data. StimulDX is based on the DirectX library from Microsoft which is mainly used for programming highly efficient 2D/3D computer games. DirectX allows synchronization with the vertical blank as well as efficient access of hardware like mouse, keyboard and joystick. StimulDX also includes routines for reading and sending TTL triggers which may be used for synchronization of stimulus presentation with  MR or EEG / MEG recordings. We have already prepared a number of easy modifiable paradigms including retinotopic mapping, presentation of image, sound and movies, short-term memory, eye movement and visual attention.

BrainVoyager 3.5

The latest version of BrainVoyager is available now! If you are a customer but you did not receive BrainVoyager 3.5 yet, please contact Brain Innovation immediately. The main new features include important routines for the analysis of event-related fMRI studies such as slice scan time correction and automatic generation of across-study / across-subject event-related averaging graphs. Another new feature is a fully automatic segmentation of the two hemispheres of a high-resolution T1 data set based both on Talairach masking and analysis of signal intensity histogramms. The interactive manipulation of surface meshes has been optimized working now up to 400% faster due to general code optimazations as well as the generation of triangle strip representations. A full description of all new features in form of a downloadable document file will be posted soon.
