Importing EEG data

Because BrainVision Analyzer (BVA) only supports certain formats of raw data, after recording data in a collection program, you may need to export and convert the data in EEGLAB successfully use it in BVA.

NetStation users: Raw data will need to be exported as a binary file (.raw) and then converted to three files in EEGLAB (.dat, .vmrk, and .vhdr). This is the only way to ensure that the raw data and events presented while recording are in sync when moving the data to analyze in BVA. Other formats may not carry over the event files presented during recording or may alter the raw EEG data.

Converting a NetStation file to a .raw file in NetStation:

1. In the main directory of NetStation (this can be navigated to by selecting the NetStation application from the bottom toolbar of the desktop), select Waveform Tools.
2. In the top window, import or drag/drop the collected NetStation file you want to convert.
