Problem with MatlabSignalProcessing

Post by yunii » 08 Jun 2021, 10:05

I am using the MatlabSignalProcessing module.
I get the following error message after a few seconds:

2021-06-08T21:54:30 - BCI2000 Started.
2021-06-08T21:54:30 - SignalSource: Waiting for configuration ...
2021-06-08T21:54:30 - SignalProcessing:
Waiting for Matlab to start up ...
2021-06-08T21:54:30 - SignalProcessing error, MatlabFilter::Publish:
Could not start Matlab: The system cannot find the file specified. (0x00000002).
2021-06-08T21:54:30 - SignalProcessing error, MatlabFilter::Publish:
Could not connect to Matlab.
2021-06-08T21:54:30 - SignalProcessing error:
Lost connection to SignalProcessing.
2021-06-08T21:54:31 - Application: Waiting for configuration ...

I have tried to started up the full path to the Matlab executable from the command line, but failed. It shows that 'MatlabSignalProcessing: Could not connect to operator module.'
Hopefully, some of you could point me into the right direction to solve this problem.

Thanks!

Hi,

you need to enter the path to the Matlab executable into the batch file you use to run Matlab signal processing, not run MatlabSignalProcessing from a separate cmd line.

Let me know whether this solves your problem.
