Re: Ubuntu 11.04 - building failed
That is indeed weird. Does the folder openvibe-modules exist in your openvibe/trunk directory ?

Hello dejwit,
could you please try to run
Also, did you modify your linux-init_env_command file?
Cheers

Re: Multiclass classifier
Hello Rapten, a quick hint: in OpenViBE you can select a box and press F1 to view its own documentation in your browser. Now, the voting classifier has several parameters (you can see their detailed description in the documentation) but basically the output class will be equal to the stimulation set...

Re: Replace the letters in P300 application with pictures
Hello,
Glade designer 3.4.1 is actually a very old version. On our Windows machines we use Glade 3.6.6 (which is already quite old as well). You can download this version here : http://ftp.gnome.org/pub/GNOME/binaries ... lade3/3.6/

Re: Experiment based on the P300-speller
Hi Stefan, About the sounds: I intended to add a voice for each letter or picture. For example, if the user wants to spell the letter A, then a voice says ‘A’ will be played when this letter is chosen, for providing audio feedback. Is it possible to do so with OpenViBE? OpenViBE provides a box which...

Re: Surface laplacian (spatial filter)
Hello Rapten, the purpose of a spatial filter is to create the best possible linear combination of electrodes in order to obtain signal with least noise possible and to maximize the contribution of each channel to the 'useful' signal. It is thus important to know what you are actually searching for ...

Re: Experiment based on the P300-speller
Hello stefan, thank you for using OpenViBE. I'll try to answer your questions to my best 1. If you use the xDAWN scenarios then, in theory, there is nothing to modify inside. The xDAWN spatial filter will select the best electrodes on its own. 2. It is possible, you will have to edit the .ui file in...

Re: P300 Visualization and icons
Hello stefan, welcome to the forums. Some time ago we have switched from using libglade to gtkbuilder to make the OpenViBE interface. The changes impact only the C++ code used to interact with the user interface files. The Glade Interface Designer is capable of editing .glade as well as .ui files an...

Re: trouble building openvibe on linux
Hello, it is normal that the BLiFF dependency is not found. It is not necessary for OpenViBE and it is NOT supported by our team. As for your problem, can you please check the log file in scripts/software/log/native-packages.log ? I am currently installing openvibe in ubuntu 10.10 to see where could...

Re: trouble building openvibe on linux
OpenViBE uses Ogre version 1.7.1, as the Ogre API changes very frequently, even for minor revisions it is quite possible that it will not work with ulterior versions.
Can you post the output of your linux-build to know where it fails, also, does the linux-install-dependencies script output any error?

Re: trouble building openvibe on linux
For the lib/OGRE folder it is as expected, there should be more libraries directly in the lib folder as well, such as the libOgreMain.so I think that the problem is that during the compilation of OpenViBE the build process used your native ogre installation. A simple solution would be to uninstall y...

Re: trouble building openvibe on linux
Hello, looking at the path from which the error comes from it seems like OpenViBE is trying to use a native Ogre installation. It indeed seems that the ogre dependency was not correctly (or at all) built by the install dependencies script and that OpenViBE now links to an Ogre installation made prev...

Re: stimulation listener vs/ signal display
Hi,
could it be possible that the window of the signal display is too small to fit all of the received stimulations and thus some of them overlap? In case of doubt I would believe the stimulation listener as the signal display box is getting quite old.

Re: Emotiv EPOC driver status
Hello Rapten,
could you please show us the scenario which you are using ? In order for the map signal displays to work they have to have positions of the electrodes. You can find examples of scenarios using these displays in dist/share/openvibe-scenarios/box-tutorials
Cheers

Re: Inter-channels operations
Hello Matthieu and welcome to the forums,
you can use the Simple DSP box to do what you want. Since this box operates on signals rather than channels, you will have to use the channel selector box to split your signal into channels and then a signal merger to put them back.
hope this helps,
Jozef
