MATLAB Scripts
At different stages in the program, BESA offers export of processed data for subsequent offline analysis. The following scripts allow to import data exported by BESA into MATLAB, e.g. to perform statistical analyses of BESA output across subjects. To download the scripts, please click onto the links below.
waveforms.m: Use this script to perform statistical analysis on exported BESA source waveforms. Features include:
- Import and graphical display of source waveforms
- Averages of source waveforms across subjects or conditions
- Computation of confidence intervals around averages using bootstrapping
- Automatic peak latency and amplitude analysis
- Computation of areas under waveforms
readBESAImage.m: Import of BESA 3D image data (multiple source beamformer / minimum norm / multiple source probe scan / sensitivity image) (*.dat)
readBESAtfc.m: Import of BESA time-frequency data (power, amplitude, TSE, coherence) (*.tfc)
readBESAbsa.m: Import of BESA source models (*.bsa)
readBESAswf.m: Import of BESA source waveform files (*.swf)
readBESAmul.m: Import of BESA ASCII multiplexed data (*.mul)
readBESAavr.m: Import of BESA ASCII vectorized data (*.avr)
readBESAsb.m: Import of BESA simple binary data (*.gen / *.dat)
