BESA Research 5.3.9 April 2012
BESA Research 5.3.9 April 2012 is the latest version of the BESA Research series. Compared to BESA 5.2, the 5.3 series provides the the following new features:
- Interaction with BESA MRI: EEG / MEG data can be coregistered with individual MRI data using individually digitized electrode positions or headshape points and also using 10-10 / 10-20 standard electrodes offered by BESA. Thus, source localizations can be displayed on the individual MRI even if no individual digitization of electrodes has taken place.
- MATLAB interface: The new MATLAB interface allows to combine the high-end data analysis capabilities of BESA Research and MATLAB, e.g. to perform automatized cross-subject statistical analysis on BESA Research data in MATLAB. Final or intermediate results of EEG/MEG data analysis can be transferred directly to MATLAB. MATLAB commands, scripts or functions can be called directly from BESA Research and applied to the provided data using BESA Research batch functions.
- CLARA - a new iterative, focusing 3D imaging method: CLARA (Classical LORETA Analysis Recursively Applied) is a newly developed iterative distributed imaging technique. Iterative 3D imaging methods aim at reducing the blurring of focal brain activity that is inherent to distributed imaging techniques while keeping the advantage of a predefined distributed source model.
- Inter-trial phase locking (ITPL): ITPL is a measure for the phase consistency of the oscillatory response of a single surface or source channel across multiple trials.
- New montaging options: The range of possibilities to create new montages has been extended: It is now possible to define the averages of user-defined channels as a reference, to compute user-specified weighted sums and differences of channels' signals, and to define virtual electrodes at arbitrary scalp locations.
- New default regularization constants for 3D source images: Each 3D source imaging technique can now be assigned its own regularization parameters.
- Windows 7: BESA Research officially supports the Windows 7 operating system.
- Postscript export: The option to export Top View screen content in encapsulated postscript format (eps) has been re-implemented in BESA Research 5.3.
- Menu-guided check for program and dongle updates
- Leadfields can now be exported
- Electrode position files of the current montage can be directly exported
Please note that you have to pay for an upgrade from BESA 5.2.x to BESA Research 5.3.x (the upgrade requires a new HASP protection key).
Complete setup: You can download the complete setup file for BESA Research from the following link: Setup_BESA_Research_V.5.3_April_2012.exe (469.361.152 bytes) Click here for a list of changes with respect to the previous version.
Trial version: If you would like to test BESA Research without owning a license yet, you can receive a fully functional, time-limited trial version. Please order a trial HASP dongle using the Trial Order Form.
