Functional Description

The Blackrock source module is used for acquiring recordings from the Blackrock NSP through CereLink (https://github.com/dashesy/CereLink). It also happens to be one of the first BCI2000 SignalSource modules to function under Linux. This documentation explains the parameterization and specifics on how to set up the system.

Parameters

The following parameters are available for configuring the Blackrock source module. You will find these parameters in the Source -- Signal Properties section.

SourceCh

"Source:Signal%20Properties int SourceCh= 144 // number of digitized and stored channels

AnalogCh

"Source:Signal%20Properties intlist AnalogCh= 0 // Analog channels to acquire from Blackrock

SignalFilter

"Source:Signal%20Properties int SignalFilter= 0 // Filter to apply to data:

• 0 -- No Filter
• 1 -- HP 750Hz
• 2 -- HP 250Hz
• 3 -- HP 100Hz
• 4 -- LP 50Hz
