BrainVision Recorder and BrainVision Analyzer 2 are pretty smart. They know the theta/phi coordinates for all electrodes named in the 10-20 System (and its extensions). So, when channels are named following this nomenclature, both Recorder and Analyzer 2 already know the electrode positions. But what if a cap layout doesn’t follow this naming convention? Or what if you need to save the standard 10 -20 electrode positions in the header file? In this case, the Recorder workspace wizard allows you to import electrode positions. This is done by means of a Brain Vision Electrode File that has the extension .bvef.
On the second page of the workspace wizard, click on the Use Electrode Position File button. A new window will open. Here you can use the Browse button to locate the electrode file (.bvef) that you would like to use. Once you have selected the relevant electrode position file, click on the Import amplifier channel table button. This will make sure that the positions are imported into the channel table in the workspace.
To import electrodes positions into your Recorder workspace go to the second page of the workspace wizard and do the following: 1. click on the Use Electrode Position File button, 2. use the Browse button to locate the electrode file (.bvef file), 3. click on the Import amplifier channel table button. Once you have completed these three steps click on OK to close the window.
