Different sources

[gsudre]

Hello,

I was wondering if anyone has experience using BCI2000 with two separate sources. For example, using gUSBAmp to record brain signals and NIDAQ for an analog signal that controls the cursor in the Application.

Is this a feasible scenario? How would you set that up (i.e. two source modules)? If it requires changes in the code, how can we make sure signals are still synchronized?

Thanks,

Gus

Gus,

Synchronizing two pieces of hardware that sample at different rates (even if set to the same rate, they will always be slightly different) is difficult, regardless of what software you use. For your purpose, it may be easier to write a little program that reads an analog signal from somewhere and then inject it into the BCI2000 control signals using the AppConnector protocol.

Gerv,

Thanks for the answer. Yes, this solution should work fine.

Best,
