Re: Python3 Modules could not be found

Hi Nathan,

Would you be able to share your build logs ?

The best would be the logs of a fresh build, running the following:

Code: Select all

rm buid; build.cmd > build.log
I hope to find information in there.

Thank you,
Thomas

Re: NIRS-Neurofeedback using OpenViBE and Aurora

Hi, Thanks for sharing the scenario. The issue I was worried about is actually not happening here, and the scenario seems fine. If I understand well, you are sending the stimulations from OpenViBE to Aurora, via the LSL Export Box, which seems to be sending way too many stimulations, right? Could it...

Re: Getting markers in EEG signal

Hi Lisa, In the controller script, there is a using directive "using LSL4Unity", which contains the liblsl class. I'm guessing LSL4Unity is therefore not present (although it should have triggered an error on the using directive before the use of liblsl). It should be in the following folder: Assets...

Re: NIRS-Neurofeedback using OpenViBE and Aurora

Hi,

I sent you a private message but it seems that you have not seen it. Hopefully you will see this one.

I have updated the forum settings to allow bigger attachments if you want to try again.

You can message me privately if it does not work, so we can try something different.

Thanks,
Thomas

Re: Vamp driver Failed to get last opened device

Hi,

I don't know about the lights and screen status of the amplifier.

I think the best would be to contact BrainProducts to make sure your amplifier is in working order.

Let us know when you have some news.

Re: Skeleton Generator freezing with GTK error

Hi Nathan,

I found the specific issue and it was, as expected, linked to the '/' character in the category.

I've pushed the fix on the development branch of the repository 'extras', you can pull it if you want.

Cheers,
Thomas

Re: Skeleton Generator freezing with GTK error

Hi Nathan, Thanks for the debugging, I could reproduce the error. I'll keep you updated on the fix. Note that once the files are generated, you can easily modify the header file to update the category to signal processing/epoching if you want. Let us know how your box development goes, we could pote...

Re: Vamp driver Failed to get last opened device

Hi, I don't have this amplifier to test, but you could try older versions of OpenViBE, such as 1.3.0 or 1.2.0 that you can get here . faGetCount() is a function from the BrainProducts API that provides the connected amplifiers count, and the error message indicates that it didn't detect any. Also, i...

Re: Making P300 Speller Faster by reducing flashes

Hi zhangxuyf, I quickly tested modifying the p300 speller into a 3x3. I modified the .ui by removing all the letters beyond the 3x3, but not rearranging them, which means that I had a table with the following lines ABC, GHI and MNO. I used Glade in order to do this. Then I modified the p300-speller-...

Re: Getting markers in EEG signal

Hi Lisa, I haven't had the chance to test the BCIManager library, but I contacted xskola, who created it and who is also on this forum. He will hopefully be able to provide some insight. I will try to give it a test in the coming days as well. The error message seems to indicate that the BCIManager ...

Re: NIRS-Neurofeedback using OpenViBE and Aurora

Hi, I see, pressing keys to insert triggers is not very convenient indeed. That would definitely help me to see the scenario, because I am not entirely sure how everything connects. Coud you share your scenario with the problematic LSL box as well, so that we can understand where it is in the pipeli...

Re: Matrix Displays crashing Designer 3.4.0

Hi Nathan, Thanks for sharing your scenarios. I was able to reproduce the issue. I also found its source and it happens to be a bug introduced in OpenViBE 3.1.0 during a refactoring. I created a ticket will have it fixed for next release, that should happen in April. Thanks for reporting this issue....

Re: Skeleton Generator freezing with GTK error

Hi Nathan, I just tried it and did not experience any issue. It might be an issue with a specific parameter or setting in the box configuration. Note that I also get the gtk-CRITICAL messages, so they don't seem to be the cause of the freeze. Could you detail the inputs, outputs settings, etc that y...

Re: Sklearn

Unfortunately the scenario cannot be stopped unless and ONLY if it is terminated with the stop button . I understand from this that the Sklearn Trainer box does not send the ExperimentStop stimulation (and it does not appear in the stimulation listener log either), right ? The Sklearn Trainer box s...
