== Note and general remarks==
To transform data from BrainVision Analyzer you need to convert it using MATLAB. We assume that you have it already installed on your PC and BrainVision Analyzer is configured to work with it. You will also need this script from our github page:
https://github.com/BESA-GmbH/BESA-MATLAB-Scripts/blob/main/Additional_utilities/BESAConnectivityScripts/Analyzer_to_BESAConnectivity.m
You will also need these toolboxes:
https://github.com/BESA-GmbH/BESA-MATLAB-Scripts/tree/main/MATLAB2BESA

== What to do in BrainVision Analyzer==
You need to prepare data that is in segments. You can of course apply any filtration and data processing beforehand. Then you export segments to matlab using Brain Voyager interface

== Adapt the script ==
Script Analyzer_to_BESAConnectivity.m needs to be adapted. The following lines should be changed:
*In line after "%% Add toolboxes" provide full path to MATLAB2BESA toolbox
*You may adapt where the resulting file will be saved by changing the line "FilePathName = [pwd '\BAtoBESA.generic'];"

== Finalization ==
You just need to run the script just by either pressing Run in matlab toolbar or by calling "Analyzer_to_BESAConnectivity" command.
In BESA Connectivity you open the newly created file.
