Re: Using OpenViBE with g.tec's g.USBamp in Windows

Hello,

I'm surprised if that'd be the case. Theres several different drivers in OV for gusbamp and only the legacy one is not supported, but even that is compiled in. You'll still need the gusbamp win drivers from gtec.

Cheers,
Jussi

Re: Graz visualization box - how to hide title bar?

Usual disclaimers about open source apply: with a bit of gtk coding it could probably be done 'by anybody'. ;)

Re: SSVEP detection problem

Hi Valeria, if you know any electrical engineeers, you could combine a sinusoidal signal generator (a device) to a physical phantom or directly to the electrodes. By controlling the frequency on/off physically you could try to debug the pipeline. Its a bit difficult if you dont know whats in the dat...

Ps. If the page and server code are out of sync, thats probably just a human error of not remembering to update one of them, most likely the code in this case.

Re: Communicate with an external device over serial protocol

Hi, you need to either write a new box, or use something like Python box, and then code the sending in python.

Re: high cross-valid accuracy poor prediction in online scen

Hi, thats often asked why the xval accuracy might exceed onlibe accuracy. Have you read this? http://openvibe.inria.fr/tutorial-how-to-cross-validate-better/ There could also be a bug, its not impossible. You are also not telling which amp and electrode layout you are using. We should put these poin...

Re: LabView Box Development

Which error did you get? ;) There should't be any reason I know of why you couldn't open tcp sockets from matlab scripts. You can also output data from matlab scripts (score) to designer. See the tutorial scenarios we bundle. Alternatively some hackery with simple dsp might be able to compute the sa...

Re: LabView Box Development

Hi Travis, writing boxes takes a bit of time getting familiar with the tutorials, playing around, getting intuition about specific questions. I dont remember from the topof my head, but ov 1.2.2 Acquisition Server might be compatible with later versions of Designer. Simply install both versions on t...

Re: Unsupported file format. Please use only WAV or OGG file

Not sure what could be wrong. If the audio part of the scenario is not critical to you, you can remove or disable the box to sidestep the problem. Do other users have issues on 64bit version of OV with the sound player or does it work? Long term solution might be to develop a more modern box with so...

Re: How to connect Enobio driver with Openvibe

Hi Umar, this issue likely originates from the Enobio driver code in the Acquisition Server. Its not related to designer or scenarios. Without having access to the device at Inria its difficult to guess what could be wrong. The driver code was a contribution from NeuroElectrics. They might not be fo...

Re: Unsupported file format. Please use only WAV or OGG file

Hi,

thats probably the sound player box. It works for me on Windows 10 + 64bit build, but I think I saw the same error on a virtual machine without soundcard emulation.

Do you get the same result with the sound player tutorial?


Cheers,
J.

Re: Scenario Control box not found

Hi Danny, the 'Scenario Control' is actually a 'Button VRPN Client' box which has been named as Scenario Control. If the box is missing it is likely that the VRPN dependency has not been successfully found and used during the compilation time. Look at the build logs and if its the case that its miss...

Re: Stimulation based epoching cannot work on overlapped sig

Hi, the stimulation based epoching only works on continuous streams apparently. Such streams have data chunks with each having timestamps like chunk: 1 2 3 4 ... stamp: [a,b][b,c][c,d][d,e] ... and so on. The end of previous chunk must exactly match in time to the start of the next chunk. You can us...
