Iuri, you're right, those coefficients aren't stored in the GDF file. They are part of the signal processing pipeline we used for motor movement imagination (the GDF file only contains signal, no signal processing there). Such coefficients could be learned or optimized offline from previously record...

iuri,

as I was writing my last message, I realized that the documentation for the spatial filter was almost empty so I used our discussion to update this documentation. You can see it on the spatial filter dedicated page. I'm waiting for your feedback

Best regards,

mcongedo,

do you have a specific need for a bluetooth support on the TMSI porti 32 / Nexus32 ?

We have such hardware here so if you have urgent need on this feature, I can give it a try (I don't know python very well, but I guess I can translate this code to C++ )

Yann

No problem, I'm happy that it's working

Iuri, the spatial filter generates a number of output channels from another number of input channels, each output channel being a linear combination of the input channels. For example, lets say ICj is the j th input channel, OCk is the k th output channel, and Sjk is the coefficient for the j th inp...

EEGHelp, I don't understand what you want to say here.

Yann

Enjoy

Hello _In_, thank you for your interest in OpenViBE and welcome on this forum, It looks like you don't have gtk development files installed. The ./linux-install_dependencies script should have compiled a version of this library but it looks like it did not. What linux distro are you using ? (after s...

As you can see, the GDF file reader complains about an invalid GDF file. Either the file is not present, or the file has been corrupted in someway. Can you configure this box to test with another GDF file ? You should be able to find a sample GDF file in the openvibe-scenarios

Best regards,
Yann

Hello EEGHelp,

Did you actually press the "run" button on this screenshot ?

Yann

Hello Iuri, congratulations for your efforts ! The openvibe repository is divided in several projects, each project corresponding to a specific part of the software. I guess you are looking for the box codes. This can be found in the openvibe-plugins subfolder and is again divided in several categor...

Hello EEGHelp,

what does your console say ? Are there any warning about file not found or something like this ?

Best regards,
Yann

Hello, this box is for playing a sound file when a specific stimulation occurs. The implementation of this box has been done "quick & dirty" : no windows implementation, and linux implementation simply cat s the file on /dev/dsp . Now that you know those limitations, you can understand that this box...

Hello mswynghedauw and welcome on this board, thank you for your interest in OpenViBE. There is no audio playback functionality in OpenViBE yet... There is no such correlation computation either. I guess that reading a sound file based on some well chosen dependencies could be straight forward, resu...

Hello and welcome on this board ! Sorry for late reply, I didn't see your post until this morning ! I don't know what QQEG means. However, averaging over time already exists in OpenViBE (see the epoch average box). You could use several of this box with corresponding filtering and 2D Topography map ...
