OpenViBE forum

Hello and welcome on this board. You can download the source code from the download page on the website. You will also get information on how to get the latest copy of the sources from the INRIA gForge. Good luck for reading the 150,000+ lines of code ;) Feel free to read the documentation pages . I...

Hello mswynghedauw and welcome on this board,

the modular EEG driver is not yet included in the official release of OpenViBE. There are a couple of details to tweak before definitve inclusion... But you can find the driver and include it in the acquisition server yourself based on this post

Ok, one second was not true
so it is less than 6 seconds.

No, because if it does not check, it can't build modified things anymore. If you run Windows and have an antivirus running, you can disable on-access scan. That would speed up things. On my Linux box, it takes less than a second. I'm sorry to tell you that after that, if you need faster access, you'...

Hello ringo-ring and welcome on this board,

Your question has nothing related to the original topic, so I moved it in another thread. Please, continue the discussion there.

Yann

ringo-ring asked in this thread an off-topic question I'll answer here : How to rebuild only OpenViBEAcquisitionServer? Running whole win32-build.cmd takes a lot of time... The build win32-build.cmd script looks for modified files and compiles / links only those files / projects. If you only want to...

Someone reported a similar problem on Linux today.

Screen color depth should be 24 or 32 bits. I will check if that can be solved for lower color depths.

Yann

Hello duvi and welcome on this board. You will find a sample GDF file in the included sample scenarios (see in share/openvibe-scenarios/signals ). I have memories that the "GDF file reader" developer told me some things about that different sampling frequencies problem in GDF files. I don't remember...

Lin,

great that you achieved installing OpenViBE on other computers. I will include Visual Studio 2008 redistributable package in the next release for sure.

For the IRC stuff, I am connected on the channel daily so you can come and contact me there whenever you want.

Yann

Lin, I can't see anything abnormal in the log files you sent. Your problem is very strange and I'm afraid that the forum won't be the most appropriate way of communication to solve it. Would you join on the IRC channel #openvibe on irc.freenode.net so we can discuss & test this live ? You can PM or ...

hmm.. Okay then, so my 2 channel ModEEG isn't enough to display topographic map. sure it's not. How about color differentiation in signal display's multi-view? Sorry I forgot to answer this one :p we do not have such functionality for now and I experienced this need recently too... I guess it won't...

Hello Lin and welcome on this board, the problem you are reporting sounds very strange (this is a first time :) ). Are you using 64 bits architecture ? Have you tried reinstalling OpenViBE ? Did you need to install Visual Studio 2008 redistributable package ? Are you sure you have XP SP2 (sorry for ...

ariandy, the channel localisation tells the 2d topographic map visualisation where the electrodes are actually located on the scalp. In order to do this, the channel names from the channel localisation must be the same as the names of your signal channels. For an example, check the share/electrode_s...

Kajenx, the reason we use left / right hand and foot movements is because signals related to this brain activity have been studied a lot. Theese signals are known to react in some specific frequency bands and in specific spatial places on the scalp (in the left and right motor cortex). Because of th...

ariandy, thank you for your interest in OpenViBE and welcome on this board. As you stated in your last message, no you can't move compiled binaries on Linux from a distribution to another. Most of the time, it won't work, except if you statically linked everything. The best thing you could do to sav...
