State Machine Internal Error

Hi Developer of Bpod,

This is Wei. I've encountered the below error for many times. I've tried to restart the matlab before running the bpod, but it seems the error occurs randomly. Your help is highly appreciated!!!

Error: Invalid op code received

Error in NewLaunchManager>LaunchProtocol (line 779)

Error while evaluating DestroyedObject Callback.

This randomly happened during the session. i.e., in a random trial number. Once this happened, I have to restart the protocol.

Hello Wei,

Please share a few details about your setup:

State Machine model (r1, r2, r2.5, r2+)
MATLAB version
Operating system
What modules and other devices are connected to the state machine

Please also send your protocol .m file to support@sanworks.io.

Thanks,
Josh

Hi Josh,

Thanks for such a quick response.

State Machine model (r1)
MATLAB version: 2023a
Operating system: windows 11
What modules and other devices are connected to the state machine:
Zaber motors, Janelia lick detection board, several breakboard.

I will send you the protocols.

Thanks again!

All my best,
Wei

Hello Wei,

Great, thanks. Looking forward to the protocols.

Two more questions:
-What Bpod version (from the lower-left corner of the Bpod Console)?
-How are the Zaber motors interfaced with the state machine?

Thanks,
Josh
