Supported Data Formats
BESA Research supports most major EEG and MEG file formats. Most file format readers are written by ourselves, others are supplied by the manufacturers. This document gives an overview of all the data formats that can be imported in BESA Research 6.1. If your file format cannot be found in this list, please contact us via our support form: BESA support form
The latest installers for the various file formats can be downloaded from the following site: BESA file format readers

If files are in one of these formats, they can be read directly and conversion is not required. BESA Research also has a new, flexible interface for importing ASCII files which can be used in conjunction with the ASCII export functions of your software. Any EEG format can be converted to the compressed BESA binary format, ASCII format, EDF+ or simple binary format.
