Re: How do you create an OpenVibe installer?
Hi Anton, We are using NSIS to compile our installers on windows. You would have to download NSIS, and maybe modify the fils scripts/openvibe-x.x.x-svnXXX.nsis . For example, this script need to package all the dependencies. Be careful if you have some new ones. If you have NSIS on your computer, ju...

Re: Default behavior of "stream switch" box?
Hi Anton, The default behaviour is indeed not to send anything until one output has been activated by a stimulation. Adding a setting for a default output is possible. I would prefer activating by default the first output, it's simpler and does not require an update of the boxes in existing scenario...

Re: starting with openvibe
Hi, As specified in the documentation page, the CSV Reader box is marked as unstable. It means the original developer thinks the box has some unexpected behavior or bugs, and its structure may change in future. You can still use this box, by allowing unstable boxes in the openvibe designer. Modify y...

Re: OpenVibe + EPOC noise reduction question
Hi cbr0wn, I am trying to grasp the concept of how OpenVibe reduces noise from EPOC headset. The EPOC already does some noise reduction filtering inside the headset. The signal you get in openvibe is already filtered a bit. Maybe there is more information in the EPOC documentation. How does OpenVibe...

Check the documentation page for more details about the given scenarios. We also provide some data fi...

Re: Problem to build OpenVibe with visual studio 2008
Hi Jean-François, Sorry for the late reply ! If you didn't already solve your problem, here is some tips. The Visual Studio 2008 vs90 compatibility has been hidden lately, as microsoft does not provide this version of VS anymore. We didn't remove the archives from the website so you will be able to ...

Re: Implementing an connectivity algorithm and plot the resu
Hi Wang Yubo, welcome on board! 1, If I want to implement an algorithm in OpenVibe, is it possible to use external libraries such as some signal processing or mathematic related source files? Are there some rules I should follow? Several OpenViBE boxes already use some external dependencies to perfo...

Re: Classifier Processor Config file question
Hi cbr0wn, Box settings can be defined by loading a file. This file will be read and the settings set accordingly when pressing "play" in a scenario. This documentation page explains how to write such file. In the case of the classifier processor, this file contains the classifier coefficients, comp...

Re: VRPN data rate
Hi karthiks,
Producing 10 values at 100Hz frequency seems ok to me !
I believe VRPN as some internal cyclic buffer so as long as you consume the data fast enough you won't have any problem.

Re: VRPN Tutorial problem
hi wuwu622, The VRPN folder should definitely contain some file (lib, bin and include folders). The easiest way to get it back is to re-install the dependencies by executing win32-instal_dependencies.exe in scripts once again (reinstall all dependencies and not only VRPN). For your information, this...

I'm reading up on the OV documentation as well as the OSC protocol. I'd like to point out that my programming skills are, at best, rudimen...

Re: Acquisition server and g.mobilab
Hi Luisa, If the drift correction is triggered too much, it can be a problem indeed. If such high drift is detected, you should have in the console a warning message telling you how much the drift was corrected. Is it the case ? Maybe the g.Mobilab+ has a jitter that need more time to adjust itself....
