Revision as of 15:02, 4 May 2021

BESA provides a file format reader that allows importing Neuroscan data in BESA Research.

Supported file format versions are

• Neuroscan Version 3.x (extensions: .cnt, .avg)
• NeuroScan Curry 6 and 7 (extensions: .rs3 .dap .dat .ce*) (this feature requires BESA Research 7.0 or higher)

Installation of file format readers

• The data reader for Neuroscan Version 3.x is already installed by default.
• To install the reader for NeuroScan Curry 6 and 7 data, run the InstallReader.exe application in the Utilities\Additional Readers\Curry7\ subfolder of your BESA Research installation (this feature requires BESA Research 7.0 or higher).

FAQ

Reading 16-bit vs. 32-bit Neuroscan data files

Neuroscan stores data either in 16-bit or 32-bit representation, but does not say so in the file format. So there is a setting in the BESA.ini file that can be set or adapted in section [Defaults]:

NeuroScanDataNumberOfBits=32

This defines the format of NeuroScan data files ('16' for 16-bit; '32' for 32-bit). If this variable is not specified, BESA uses a heuristic to (try to) decide which of the two data formats is used. This variable overrides the heuristic. If you want to specify the NeuroScan data format for specific files, create a file, named "16bit" or "32bit", and place it in the data folder.

Also see the Wiki page on the BESA.ini for more details: The Initialization File: BESA.ini
