motor imaginary CSP online 4. xml crashes

Post by yanli »

The three previous stages worked well. Finally when I try this online experiment, it would crash and quit quickly after the clicking of start.
I could only see the error in the console

. The problem is that I never have a user name appearing
in this figure, do not know where it comes from.
Could anyone give me some suggestions?

Hello.
I haven't seen this error message before.

Since there is not much information, let me ask a few questions to help you.

- Did you try scenarios 2, 3, and 4 using examples instead of your data? (example ov data) It should work.
(without any modification, scenarios 2 and 3 generate csp.cfg and classifier.cfg, respectively. Scenario 4 should load those two files, and the input EEG device should have the same number of channels)

-> If it works with example data, you need to investigate your EEG.
-> If it does not work, you need to investigate if there is a modification that makes an error within OpenViBE scenarios. / or try a different OpenViBE version.

In addition, could you try the latest OpenViBE version? I saw a few warning messages in your image; it seems that you loaded a scenario XML file written from a different OpenViBE version.

Best regards,
Kyungho Won

Hi,

In addition to Kyungho's answer, I had a look at the code, and the log actually means that you do not have any outputs on the box.
Have you changed any box configuration ?

I agree with Kyungho on the fact that upgrading to a newer version of OpenViBE would likely help.
