Hi, The box-tutorials is with other. When you open a scenario with no scenario open (or an unsaved scenario) it push you directly on box-tutorials and bci-example folder. I misspoke, the matrix classifier boxes are separate from the python boxes. Python boxes with scikit learn are in scripting / pyb...

Hi, Stimulation Code is juste a number to identifier after all. If you wan't to use only OVTK_StimulationId_Label_XX for all of your stimluation it's your choice. Just your analysis and data sharing can be hardest. Stimulation with prefix GDF_ correspond with standard code of gdf format (for eeglab ...

Hi, Last Time I say that to you : don't send private message in addition of your posted message, I have enough spam without that. I answer whenever I come and I come often. Next time I don't answer. For your question, I have implement Matrix classifier with riemmannian metric. and In pythom, there i...

HI, it depends on which metadata you want to go from one box to another. If we assume that it is within OV without any external elements. The matrices already contain the name of the channels, you have the number of channels, the number of samples per channel. the signals also have the sampling info...

HI,
If it was possible the research on bci make a big jump.^^

Hi,
At the moment we are limit to only one version for compiled version.
Thibaut
Ps : if you compile your own version, it takes the version of python you have installed

Hi, LSL can't send metadata, you open a stream for one type of data. So mix string and float is not possible. If you can communicate in amont, you can set before channel name and other. The only way I see is to send each time string and cast each time data but the complexity is high for nothing. Thi...

Hi,
So you can use the spectral analysis to see value of each frequency in real time. But to have the best band, you must implement an algorithm (the fatest wy for no developper is to use python) with gradient descent or other way.
Thibaut

Hello, I'm not sure what you want to do. To limit the frequency bands, you have the "temporal filter". To separate the frequency bands and have the power of each, you have the "spectral analysis". For the average of your signal (per channel) you have the "signal average". The simple DSP will apply a...

HI,
For optionnal drivers, you need to install drivers and sdk from your installation disc on your cap box. actually we can't share automaticly the drivers needed files for this cap.
Thibaut

Hi,
Sorry the speakers have forgot to launch the recording.
Thibaut

Hi, Regarding the launch by command guest, the config file only allows you to define the driver options and the last driver used. It is not currently possible to launch it only in command prompt (without gui and in auto play). But it's a feature that could be interesting. I note it in the todo list....

I have never had this error..... Try to delete build and dist dir, take meta branch developp last commit and next for each submodule sdk, extra, designer last commit of developp (in this order because meta reinit submodule branch). Now you have the new build system. Maybe it can works....
Thibaut

Strange,
your vs2013 is the express or professionnal version ? Standard doesn't work..... Yes I know it's boring the exact good version to have...
PS : I misspoke, I wanted to say that if you had tried to build before doing the install dependencies it might not work. Not that you had to do it.^^

Hi,
Right Click on box classifier trainer, inputs->new. I have never test the behavior on 3 class for this box, so I can help you so much.^^
